[ID 20001123.006] segfault with diagnostics + Exporter + bad method

This is a bug report for perl from pixel@no.mandrakesoft.com,
generated with the help of perlbug 1.28 running under perl v5.6.0.


-----------------------------------------------------------------
[Please enter your report here]


The following code makes perl segfault (it still does so on 5.7.0):

--------
use diagnostics;
@ISA = qw(Exporter);

my $tmp = "/tmp/tmp.pl";
system("echo rubbish modulename > $tmp");

require $tmp;
--------

without the require, it doesn't fail. I used the ``system("echo...'' to make the
example fit in a single file. The same problem happens if you /tmp/tmp.pl is
already created.

the problem appeared because "rubbish modulename" was in fact 
"paackage modulename", aka a typo 


thanks, cu Pixel.
