[Octave-bug-tracker] [bug #45346] octave crashes when trying to install database package

[Olaf Till]

Follow-up Comment #6, bug #45346 (project octave):

Still stuck. The crash seems to happen when ldopen initializes globals. I
found no globals in 'database' which could directly cause a constructor call
in liboctinterp.so.2 with a stack as it follows upwards from liboctinterp.so.2
in the backtrace. I also didn't find how Octave could introduce such globals
into pq_interface.oct.

Unfortunately, liboctinterp.so.2 doesn't seem to contain file- and
line-information for debugging (although liboctave seems to contain it). If we
could see this information, this could give a clue.

Could you try to recompile Octave and make a new backtrace? You probably would
have to call 'make clean' before recompiling. Then e.g.

export CXXFLAGS='-g'

and then ./configure and make.

Still better is

export CXXFLAGS='-g -O0'

but this slows Octave down and you will have to recompile later without -O0
for your own work.
