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.
