[Octave-bug-tracker] [bug #58957] [octave forge] (sparsersb) Failure to install and crash in function

[Markus Mützel]

Follow-up Comment #37, bug #58957 (project octave):

Sorry, I'm not sure I understand what I am supposed to do.
I cross-built Octave with all its dependencies (including librsb) for Windows
on Linux with MXE Octave.
MXE Octave cleans up the build directories of each package it has built. I no
longer have a librsb build directory.
Instead, I have an msys2 environment with installed gcc and librsb. That is
the same librsb that Octave is using.
So, I ran the following at the msys2 shell:

$ gcc rsb_mtx_rndr.c -otest.exe -lrsb -fopenmp
$ gdb test.exe

Is this a meaningful test? In case it is: The test program didn't crash.
I ran the program about 20-30 times but it never crashed.

I am attaching the "crash.eps" file that was created by that program in case
that helps.

One difference is that this test program was built natively on Windows.
"sparsersb" was cross-built on Linux for Windows.
To test if that makes a difference, I re-built and re-installed sparsersb on
Windows. In Octave:

>> pkg install -forge sparsersb
warning: LFLAGS is deprecated and will be removed in a future version of
Octave, use LDFLAGS instead
For information about changes from previous versions of the sparsersb package,
run 'news sparsersb'.
>> pkg load sparsersb
>> pkg list
[...]
          sparsersb *|   1.0.8 | C:\Users\Markus\octave\sparsersb-1.0.8
[...]
>> sparsersb(sparsersb([1]),"render", "crash.eps" ,1024);


But Octave crashed on the last command.
