Segmentation fault
Does anyone have problem with Apache 1.3.12 / Mod_perl 1.24 making it's
childs do segmentation faults whenever the server requested to execute a
perl module?
If I request a piece of graphics, it works fine, but not if the page is
generated by mod_perl. I have no compile errors, all the modules works on
the previous development machine but not this newly installed machine.
The only difference I can see, is that I installed perl 5.6.0 before
installing the mod_perl apache, should that cause any problems?
The system is running on FreeBSD 4.2.

A mod_perl snapshot from CVS as of yesterday works just fine with the
stock perl 5.005_03 that is part of FreeBSD 4.2. What I do is install
apache+mod_ssl from /usr/ports/www/apache13-modssl, then install
mod_perl from a cvs checked out copy using apxs (just follow the
instructions in README.apaci).
Works great. As for moving to perl 5.6, I don't know what problems
that would cause. Perhaps you should try using the latest CVS
snapshot of mod_perl to see if that works.

5.6.1-trial1 expected by this weekend. That should include all the
recommended list of patches for 5.6.0.

Is there some place that has collected the "recommended" patches for
5.6.0? There don't seem to be any patches for it on CPAN... You'd
think that 5.6.1 would come out by now to fix up the problems people
have been having with 5.6 especially in mod_perl...

Did this not work? After applying the patch did you recompile both Perl
_and_ mod_perl?

Huh? You've built mod_perl with one version of perl, but then installed
another binary incompatible (+ different hardcoded INC) perl version and
you think to get away with that? All the new modules that you are going to
build won't work with mod_perl if they have XS in them and you build these
with another perl version... Unless you've managed to keep both
installation around, but then it doesn't matter.

A couple of days ago I asked the question below, but nobody seemed to be
able to answer it.
Well, in case somebody else runs into this problem I can tell that my
solution to the problem was to use perl5.005 and not install perl5.6.0 until
after i completed the installation of mod_perl / Apache and the modules i
needed for it.

Maybe it's this old bug:
http://www.geocrawler.com/archives/3/182/2000/6/0/3863601/
PS--Alex: Please add your message _after_ the original message, not
_before_, since otherwise long threads get hard to follow. Thanks!
RE: Segmentation fault
Posted by Alex Algard <al...@cardomain.com>.
I've seen a similar issue on our machine. We're running:
- mod_perl 1.24
- apache 1.3.12-25
- RedHat 7.0
- plenty of spare RAM
and only when we include certain of our own Perl modules in startup.pl do we
see the following in the error_log:
[Mon Dec 11 13:11:17 2000] [notice] child pid 2991 exit signal Segmentation
fault (11)
If we only use these certain modules in our mod_perl scripts (and not in
startup.pl), the segmentation faults don't occur. I was unable to spend any
time on tracking the bug down, but I'd also be curious to hear more about
this issue and any suggestions.
