Package: perl
Version: 5.8.4-2
Severity: normal
The following script reliably segfaults perl in the pop expression:
sub foo {
print STDERR "\...@_ = (",join(",",@_),")\n" ;
$arrayref = 0 ;
print STDERR "\...@_ = (",join(",",@_),")\n" ;
$_[0]->[0] ;
print STDERR "\...@_ = (",join(",",@_),")\n" ;
pop @_ ;
print STDERR "I survived!" ;
}
$arrayref = [ 17 , [19] , 21 ] ;
foo @{$arrayref} ;
Sample output:
$ perl perlbug.pl
@_ = (17,ARRAY(0x814cbb8),21)
@_ = (,,)
@_ = (ARRAY(0x814cad4),ARRAY(0x814cad4),)
Segmentation fault
$
I do not enclose a stack trace as the cause of the problem evidently
lies earlier: The assignment to $arrayref in the subroutine somehow
influences @_ in a way that the interpreter is not prepared for.
The bug also appears in perl 5.6.1-8.7 from woody.
