(poke) c
[1] 11989 segmentation fault poke
As you can see, the memory is not correctly written, and attempting to
print a value after attempting to write to the memory results in a
SEGFAULT.
I suspect that the error starts when the request to write the array of
arrays is initiated, but does not result in the memory buffer being
modified. I guess the interpreter is writing the content somewhere else
than in the buffer.
This issue was already reported upstream by another user in 2021:
https://sourceware.org/bugzilla/show_bug.cgi?id=28380
However I am not able to know if this bug is from upstream, or if the
user that reported the upstream bug was also using the Debian package.
If one can reproduce this error, eventually on another distro, we should
notify upstream that the error is still happening.
Thanks,
Agathe.
