Does not seem to be fully fixed.
Maybe I shouldn't test when being interupted by many telephone calls (but how could I have known all those calls would come?)
Anyway:
I couldn't do the PoCs before updating, because gcc wasn't installed and libgcc1 had a higher version than the available gcc, though lower than the current one in testing. (didn't dare to downgrade)
Anyway, after installing / updating to
libquadmath0-4.8.2-3.1.mga4.i586.rpm

The reason for adding the fix on mga3 gcc is that upstream says it's a regression since gcc-4.5 so I added the fix since gcc is being pushed anyway. So dont worry if the issue dont trigger, the test still confirms that the affected code for the optimizer is not regressing either :) With the updated clang/llvm, the clang test passes. Marking OK and validating. The advisory still needs to be uploaded. Please push this to core/updates for Mageia 3 and Mageia 4. Keywords:

Advisory: Updated gcc packages fixes miscompilation and clang++ compatibility Updated gcc packages fixes the follwoing bugs: The gcc rtl-optimization sched2 miscompiles syscall sequence wich can cause random panic in glibc and kernel (gcc/PR61801) clang++ fails to find cxxabi.h and cxxabi_tweaks.h during build (mga#13543) Testscase for miscompilation bug: testfile: $ cat exit.i --- int a, b, c; void fn1 () { int d; if (fn2 () && !0) { b = ( { int e; fn3 (); switch (0) default: asm volatile("" : "=a"(e) : "0"(a), ""(0)); e; }); d = b; } c = d; } --- before: $ gcc -fcompare-debug -O2 -c exit.i gcc: error: exit.i: -fcompare-debug failure (length) after: $ gcc -fcompare-debug -O2 -c exit.i (no output, exits without errors) Testcase for clang++ Testfile: $ cat clang_test.cpp --- #include <cxxabi.h> int main (void) { } --- before: $ clang++ clang_test.cpp clang_test.cpp:1:10: fatal error: 'cxxabi.h' file not found #include <cxxabi.h> ^ 1 error generated. after: $ clang++ clang_test.cpp (no output, exits without errors) SRPM: gcc-4.8.2-3.1.mga4.src.rpm i586: gcc-4.8.2-3.1.mga4.i586.rpm gcc-c++-4.8.2-3.1.mga4.i586.rpm gcc-cpp-4.8.2-3.1.mga4.i586.rpm gcc-doc-4.8.2-3.1.mga4.noarch.rpm gcc-doc-pdf-4.8.2-3.1.mga4.noarch.rpm gcc-gfortran-4.8.2-3.1.mga4.i586.rpm gcc-gnat-4.8.2-3.1.mga4.i586.rpm gcc-java-4.8.2-3.1.mga4.i586.rpm gcc-objc-4.8.2-3.1.mga4.i586.rpm gcc-objc++-4.8.2-3.1.mga4.i586.rpm gcc-plugins-4.8.2-3.1.mga4.i586.rpm gcj-tools-4.8.2-3.1.mga4.i586.rpm libasan0-4.8.2-3.1.mga4.i586.rpm libasan-devel-4.8.2-3.1.mga4.i586.rpm libatomic1-4.8.2-3.1.mga4.i586.rpm libatomic-devel-4.8.2-3.1.mga4.i586.rpm libgcc1-4.8.2-3.1.mga4.i586.rpm libgcj14-4.8.2-3.1.mga4.i586.rpm libgcj14-base-4.8.2-3.1.mga4.i586.rpm libgcj14-src-4.8.2-3.1.mga4.i586.rpm libgcj_bc1-4.8.2-3.1.mga4.i586.rpm libgcj-devel-4.8.2-3.1.mga4.i586.rpm libgcj-static-devel-4.8.2-3.1.mga4.i586.rpm libgfortran3-4.8.2-3.1.mga4.i586.rpm libgnat1-4.8.2-3.1.mga4.i586.rpm libgomp1-4.8.2-3.1.mga4.i586.rpm libgomp-devel-4.8.2-3.1.mga4.i586.rpm libitm1-4.8.2-3.1.mga4.i586.rpm libitm-devel-4.8.2-3.1.mga4.i586.rpm libmudflap0-4.8.2-3.1.mga4.i586.rpm libmudflap-devel-4.8.2-3.1.mga4.i586.rpm libobjc4-4.8.2-3.1.mga4.i586.rpm libquadmath0-4.8.2-3.1.mga4.i586.rpm libquadmath-devel-4.8.2-3.1.mga4.i586.rpm libstdc++6-4.8.2-3.1.mga4.i586.rpm libstdc++-devel-4.8.2-3.1.mga4.i586.rpm libstdc++-docs-4.8.2-3.1.mga4.noarch.rpm libstdc++-static-devel-4.8.2-3.1.mga4.i586.rpm x86_64: gcc-4.8.2-3.1.mga4.x86_64.rpm gcc-c++-4.8.2-3.1.mga4.x86_64.rpm gcc-cpp-4.8.2-3.1.mga4.x86_64.rpm gcc-doc-4.8.2-3.1.mga4.noarch.rpm gcc-doc-pdf-4.8.2-3.1.mga4.noarch.rpm gcc-gfortran-4.8.2-3.1.mga4.x86_64.rpm gcc-gnat-4.8.2-3.1.mga4.x86_64.rpm gcc-java-4.8.2-3.1.mga4.x86_64.rpm gcc-objc-4.8.2-3.1.mga4.x86_64.rpm gcc-objc++-4.8.2-3.1.mga4.x86_64.rpm gcc-plugins-4.8.2-3.1.mga4.x86_64.rpm gcj-tools-4.8.2-3.1.mga4.x86_64.rpm lib64gcj14-4.8.2-3.1.mga4.x86_64.rpm lib64gcj_bc1-4.8.2-3.1.mga4.x86_64.rpm lib64gcj-devel-4.8.2-3.1.mga4.x86_64.rpm lib64gcj-static-devel-4.8.2-3.1.mga4.x86_64.rpm libasan0-4.8.2-3.1.mga4.x86_64.rpm libasan-devel-4.8.2-3.1.mga4.x86_64.rpm libatomic1-4.8.2-3.1.mga4.x86_64.rpm libatomic-devel-4.8.2-3.1.mga4.x86_64.rpm libgcc1-4.8.2-3.1.mga4.x86_64.rpm libgcj14-base-4.8.2-3.1.mga4.x86_64.rpm libgcj14-src-4.8.2-3.1.mga4.x86_64.rpm libgfortran3-4.8.2-3.1.mga4.x86_64.rpm libgnat1-4.8.2-3.1.mga4.x86_64.rpm libgomp1-4.8.2-3.1.mga4.x86_64.rpm libgomp-devel-4.8.2-3.1.mga4.x86_64.rpm libitm1-4.8.2-3.1.mga4.x86_64.rpm libitm-devel-4.8.2-3.1.mga4.x86_64.rpm libmudflap0-4.8.2-3.1.mga4.x86_64.rpm libmudflap-devel-4.8.2-3.1.mga4.x86_64.rpm libobjc4-4.8.2-3.1.mga4.x86_64.rpm libquadmath0-4.8.2-3.1.mga4.x86_64.rpm libquadmath-devel-4.8.2-3.1.mga4.x86_64.rpm libstdc++6-4.8.2-3.1.mga4.x86_64.rpm libstdc++-devel-4.8.2-3.1.mga4.x86_64.rpm libstdc++-docs-4.8.2-3.1.mga4.noarch.rpm libstdc++-static-devel-4.8.2-3.1.mga4.x86_64.rpm libtsan0-4.8.2-3.1.mga4.x86_64.rpm libtsan-devel-4.8.2-3.1.mga4.x86_64.rpm Reproducible: Steps to Reproduce:
