IMPORTANT: Mysterious errors in perl patch level 8, solved

[Anders Pilegaard]

We have an installation with sun-2's, sun-3's, sun-4's and
hp-9000's running perl.

After installing patch 7 & 8 some PERL-scripts started
dumping core.  Some scripts even produced wrong results !
Running them under perl -d produced strange error messages
concerning memory allocation, alternately running without
errors at all.  It seems to be the patch to restore
registers after longjmp's that provoked this behaviour.  At
our site we have solved the problem by compiling 'cmd.c'
with JMPCLOBBER defined.

As far as we can tell, this problem manifests itself on all
of our machines, albeit in different disguises.
