I never used this program before, just wanted to see what it do. I browsed around in it a few seconds then it vanished from screen. Starting it in terminal and not touching it at all, it crash after about ten seconds, with a lot of output. Notably the lines: *** longjmp causes uninitialized stack frame ***: plasma-discover terminated ======= Backtrace: ========= /lib64/libc.so.6(+0x72435)[0x7f6b649a7435] /lib64/libc.so.6(__fortify_fail+0x37)[0x7f6b64a3c3a7] /lib64/libc.so.6(+0x1072dd)[0x7f6b64a3c2dd] /lib64/libc.so.6(__longjmp_chk+0x29)[0x7f6b64a3c239] /lib64/libcurl.so.4(+0xe4e5)[0x7f6b1d6e04e5] /lib64/libc.so.6(+0x338a0)[0x7f6b649688a0] /lib64/libc.so.6(__poll+0x2d)[0x7f6b64a1efcd] /lib64/libglib-2.0.so.0(+0x49e14)[0x7f6b6009be14] /lib64/libglib-2.0.so.0(g_main_context_iteration+0x2c)[0x7f6b6009bf2c] /lib64/libQt5Core.so.5(_ZN20QEventDispatcherGlib13processEventsE6QFlagsIN10QEventLoop17ProcessEventsFlagEE+0x66)[0x7f6b65634776] /lib64/libQt5Core.so.5(_ZN10QEventLoop4execE6QFlagsINS_17ProcessEventsFlagEE+0xea)[0x7f6b655dfe0a] /lib64/libQt5Core.so.5(_ZN16QCoreApplication4execEv+0x88)[0x7f6b655e89c8] plasma-discover[0x41045e] /lib64/libc.so.6(__libc_start_main+0xf0)[0x7f6b64955600] plasma-discover(_start+0x29)[0x410569] This system is mga6 64 bit with all updates from updates_testing excluding kernel which is desktop 4.14.70. Originally a mga4 system, it may have some cruft laying around. I uninstalled plasma-discover and reinstalled, no change. Could this be a variant of Bug 22828 ? Op there say it vanished in a few seconds without touching it so timing seem similar.

Since some month ago i also use updates_testing repos, also for update. Regardless of how it gets trigged here, the error " longjmp causes uninitialized stack frame " to mee seem like a design/compile fault that should get fixed.
I strictly use dnf and have all i586 repos disabled ( # dnf config-manager --set-disabled ... ). It is also a Mageia 6 installation, no system upgrade from Mga 5.
Searching web for "*** longjmp causes uninitialized stack frame ***" gets some hits on bug reports for other programs, and several point out a bug in curl, but which was fixed long ago in version 7.32 ...? i.e see: https://stackoverflow.com/questions/9191668/error-longjmp-causes-uninitialized-stack-frame
So maybe a returning curl bug?

This bug relates to Mageia 6, no longer supported; and an old version of the software. Having just installed it on Mageia 7, discover-5.15.4-2.mga7, it works. Running under Plasma, both from the menu [Tools-System Tools] and console [$ plasma-discover]. The console O/P is voluminous. @ Ulrich Morgan: please can you say whether you still have the problem on Mageia 7? If not, please close the bug OLD.

MGA7-64 Plasma Nvidia seem OK; installed discover-5.15.4-2.mga7 launched "plasma-discover", Browsed around about a minute Installed KDEConnect, and find it working
Status: NEW => RESOLVEDResolution: (none) => OLD
Now when i closed discover-plasma, in the terminal from where i started it, it outputs PackageKit stopped running! Could not stop all fwupd threads And i have to issue ^C to get the cursor back. And yes the output when it is running is voluminous. I.e a lot of: "Could not convert argument 0 at" "expression for iconName@qrc:/qml/KirigamiActionBridge.qml:35" "Passing incompatible arguments to C++ functions from JavaScript is dangerous and deprecated." "This will throw a JavaScript TypeError in future releases of Qt!" qrc:/qml/KirigamiActionBridge.qml:34:5: Unable to assign [undefined] to QString So the shape of the program is "working, but not perfect"
