[Octave-bug-tracker] [bug #53330] [octave forge] (control) several functions crash Octave with SIGABRT from invalid free

[Mike Miller]

Follow-up Comment #5, bug #53330 (project octave):

For full exhibition, I debugged this by installing the libblas3-dbgsym and
liblapack3-dbgsym packages from Debian, which add debug symbols for their
internal functions. I also installed the lapack Debian source package so I
could get exact line numbers.

I then ran Octave with valgrind again and got the exact LAPACK source file and
line number where the invalid write took place (dgees.f:408). And it was
obvious that it was trying to write into the LOGICAL BWORK array that was
passed in.
