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

[Olaf Till]

Follow-up Comment #4, bug #45346 (project octave):

Ok, that backtrace is more information. Sorry for having been sarcastic
before.

I forgot that the lookfor cache is created already at install time (allthough
we just recently had a problem due to this code in pkg ...). I'd say the
problem can only occur in non-root installs (but even so I can't reproduce it
...).

But I'll have some problems with the backtrace. In the past there was a
problem due to undefined order of initialization, but I can't see something
pointing to any constructors of 'parallel' in the backtrace. The segfault
occurs after dlopen, after going through a stack of Octaves internal
functions. It's difficult to find out a relation to something in the loaded
shared binary (pq_interface.oct). Although it looks suspicious that an Octave
function _dl_catch_error is called; but that probably should not lead to a
segfault.

I'll need some time for this, and success is doubtful since I can't reproduce
the issue. It may turn out that the problem is in Octave; maybe an insider has
a clue, sparing me some digging.
