Bug 29164

That earlier bug's update is ready to push, blocked by this new one - which reiterates the need to report the fault (ineffective fix) upstream. Who does this?
I just have - by appending to their bug (131), which is currently closed.
I do not know whether to leave this with Bugsquad, or assign to packagers; with its UPSTREAM status.

Status: NEW => UPSTREAM

Assigning globally.

Fixed in mga9

Status: UPSTREAM => NEW
CC: (none) => mageia
Version: Cauldron => 8
Whiteboard: MGA8TOO, MGA7TOO => (none)

New version pushed in mga8

src:
    - matio-1.5.21-1.mga8

Status comment: Incomplete fix needs to be reported upstream => (none)
Assignee: pkg-bugs => qa-bugs

We'll have to see if it's actually fixed.

matio-1.5.21-1.mga8
libmatio-devel-1.5.21-1.mga8
libmatio11-1.5.21-1.mga8

from matio-1.5.21-1.mga8.src.rpm

mga8, x64

Installed the latest core packages and checked the PoC again:
$ matdump 006-memleak
InflateRankDims: inflate returned data error
InflateVarTag: inflate returned data error
Empty
InflateRankDims: Reading dimensions expected type MAT_T_INT32
      Name: 
      Rank: 0
InflateRankDims: inflate returned data error
Segmentation fault (core dumped)

Tried updating with qarepo.  Not on my chosen mirror yet.  Trying later.
Assuming that rpms are for instance:
matio-1.5.21-1.mga8.x86_64.rpm
.....

CC: (none) => tarazed25

Updated the three packages.

$ matdump 006-memleak
Inflate: inflate returned data error

That is a clean result so looks like  it is fixed.

$ urpmq --whatrequires-recursive lib64matio11
lib64matio-devel
lib64matio11
matio

No more scilab.  Cannot find it either.
Back to this later.

We had scilab in Mageia 7 so maybe it is in Cauldron?

Scilab was dropped.

ACK

Modified the 3d.c file used in bug 26883, which does not do very much but exercises matio.

#include <stdio.h>
#include <matio.h>
#include <matio_pubconf.h>

int main()
{
const int first = 2, second = 4, third = 5;
int array3d[2][4][5] = { 0 };

// fill 3d array
for (int i = 0; i < first; i++)
	for (int j = 0; j < second; j++)
		for (int k = 0; k < third; k++)
			array3d[i][j][k] = (i + 1) * (j + 1) * (k + 1);

// write
char* fieldname3d = "array3d";
const char *filename = "myfile.mat";
mat_t *matfp = NULL; //matfp contains pointer to MAT file or NULL on failure
matfp = Mat_CreateVer(filename, NULL, MAT_FT_MAT5); //or MAT_FT_MAT4 / MAT_FT_MAT73
//don't forget to close file with Mat_Close(matfp);
size_t dim3d[3] = { first, second, third };
matvar_t *variable3d = Mat_VarCreate(fieldname3d, MAT_C_INT32, MAT_T_INT32, 3, dim3d, &array3d, 0); //rank 3
Mat_VarWrite(matfp, variable3d, MAT_COMPRESSION_NONE);
Mat_Close(matfp);
Mat_VarFree(variable3d);
}

OK on the basis of this primitive test.
