This is a bug report for perl from eirik@blackbox.dav,
generated with the help of perlbug 1.35 running under perl 5.9.5.
-----------------------------------------------------------------
[Please enter your report here]
To demonstrate:
eirik@blackbox[05:14:50]~$ bleadperl -e 'local *@; eval {1}'
Segmentation fault
eirik@blackbox[05:16:50]~$
If I trace or step through the code in the debugger, it terminates
successfully at the end of the code (which made this failure a pain to
track down). Otherwise it segfaults in the debugger as well.
It's just blead, as far as I can tell. This runs just fine in 5.8.8
and older releases, as well as in maint (as of a week ago, at least).
[Please do not change anything below this line]
