 Hi Stas,

wondering if this is the XSLoader vs DynaLoader mentioned earlier today.
there is a workaround builtin to 1.27-tobe:
http://perl.apache.org/~dougm/mod_perl-1.26_01-dev.tar.gz

you could also try 'use DynaLoader ();' before loading any other modules.

 Thanx Doug for the reply. Unfortunately I still get
segfaults :-( No difference.
Once I have the time, I'll get the stacktrace  see
for any clues. Right now I have kept DSO in the
backburner, as I have got PerlFreshRestart fully up
and runnig (with a no. of patches to mod_perl)

Hi Stas,
Thanx for the reply. However, I had already read the
doc. and done everything mentioned there. I had
recompiled perl with -Ubincompat5005 as mentioned.

I've attached some additional info., generated by
trussing the child, as it was being restarted:
$truss -ef -o ~/truss.out -r0,1,2 -w0,1,2 -p 26978

Note: I have also tried setting ENV
PERL_DESTRUCT_LEVEL to -1 and also to 2, but got the
same results.
Thanx for any help.

Good then. I just wasn't sure. Hopefully someone with Solaris 
access/knowledge will be able to help you out, but see below.

 I've attached some additional info., generated by
 trussing the child, as it was being restarted:
 $truss -ef -o ~/truss.out -r0,1,2 -w0,1,2 -p 26978

What's needed is the core dump backtrace, see
