[Octave-bug-tracker] [bug #61911] testsuite segfaults on Debian armel

[Sébastien Villemot]

Follow-up Comment #10, bug #61911 (project octave):

I have recompiled Octave 7.0.90 on Debian sid armel, with ASAN, and with both
GCC and Clang.

I attach the results of exercising the testsuite with both compilers. In both
cases, I get memory bugs, though it is not the same one across compilers and
it happens much earlier with GCC.

I don’t really know what to conclude from that. If I had no issue with
Clang, I would have been tempted to conclude that it’s a GCC bug, but things
are not that simple.

Note that I’m not personally interested in Octave on armel, which is an
inadequate platform for number crunching (since it does not have hardware
floats). But since this is an architecture officially supported by Debian, as
the maintainer of the Debian package, I have no choice but to investigate
issues there. In the worst case, if we can’t find a solution, I will disable
the testsuite at build time on Debian armel, but that’s not very
satisfactory.

Also note that there are test failures with Octave 6.4.0 on Debian armel (see
https://buildd.debian.org/status/fetch.php?pkg=octave&arch=armel&ver=6.4.0-2&stamp=1642375809&raw=0).
But at least there is no crash with that version.
