Package: perl
Version: 5.8.4-8sarge6, 5.8.8-7etch6, 5.10.0-19
Severity: normal
Hi,
by accident I produced a segfault with a perl script. I stripped it
down to the following line:
perl -MData::Dumper -e 'my %c=(d=>[1,2,3]); do { push(@{c{d}}, $d); } until 1'
(Yeah, that's broken code, but that doesn't matter here. ;-)
The segfault goes away, if you either
a) remove "-MData::Dumper" -> Syntax error
b) remove ",3" -> Syntax error
c) replace "@{c{d}}" with "@{$c{d}}" -> runs the script
d) remove the do until loop -> Syntax error
The segfault happens on Etch amd64 and i386, and on Lenny/Sid amd64,
i386 and kfreebsd-i386. It even was present on the oldest Debian box I
found around (which happens to be an Sarge on i386). So I suspect it's
an upstream bug. And a not really new but still yet undiscovered bug.
In my original (much longer) script, I also got a warning about what's
unclean with the code just before the segfault:
# perl /usr/local/sbin/add-backuppc-host.pl
Scalar value @{config{dir} better written as ${config{dir} at
/usr/local/sbin/add-backuppc-host.pl line 134.
Segmentation fault
Here's a backtrace on Etch amd64:
