Really weird problems.
Hi!
I have come across a very strange problem. Suddenly we got reports that
people that logged on to our site couldn't click on one of the pages that
only members had access to, they said that Internet Explorer reported that
the page couldn't be viewed at this time. We tried to look into this but
could not reproduce the problems with our own accounts. When we tried with
one of the accounts that belonged to one of the people that reported this
we could reproduce the error.
Reading the embperl.log file shows nothing wrong but the httpd process
dies (error_log shows), but only with a small amount of the accounts and
it's completely random (but always the same accounts):
[Mon Aug 30 20:04:58 2004] [notice] child pid 44755 exit signal
Segmentation fault (11)
Anyone that has any idea of what could cause this ?

Hi Stefan,
Sorry for me late reply, but the last week was horrible full of work...
I just tried to find out what's wrong, but it's not so easy.
It would be very helpfull if you have a chance to create a small tests case,
that doesn't depends on other files, that reproduces this behaviour. Then I
could debug it here on my computer.
In case that is not so easy, please set EMBPERL_DEBUG to 0x7fffffff and
rerun it. Then send me the /tmp/embperl.log and again the stackbacktrace
(because it seems that it not always crashs at the same point)

Could you try Embperl-2.0rc1 ?
If it still segfaults, could you please compile Embperl with
perl Makefile.PL debug
make install
And again make a stackbacktrace.
