Bug summary: [RHEL5] memusage cmd segfaults if run on a perl script that has 'use' in it
Bugzilla link: https://bugzilla.redhat.com/show_bug.cgi?id=531576
Description:
Description of problem:
memusage utility is part of glibc-devel
memusage cmd segfaults if run on a perl script that has 'use' in it.
Examples:
[my_name@my_host ~]$ ./memusage --png=out.png -x 800 -y 300 ./perltest.pl
This works (contents of perltest.pl):
#!/usr/bin/perl -w
print "my_name\n";
This segfaults:
#!/usr/bin/perl -w
use Net::SSH::Perl;
print "my_name\n";
Version-Release number of selected component (if applicable):
How reproducible:

Steps to Reproduce:
1.create perl script:
#!/usr/bin/perl -w
# perltest.pl
use Net::SSH::Perl;
print "my_name\n";
2. run memusage on script:
[my_name@my_host ~]$ ./memusage --png=out.png -x 800 -y 300 ./perltest.pl
Actual results:
my_name@my_host /tmp % memusage --png=out.png -x 800 -y 300 ./perltest.pl
/usr/bin/memusage: line 253: 29483 Segmentation fault (core dumped) LD_PRELOAD=/usr/\$LIB/libmemusage.so MEMUSAGE_OUTPUT=/tmp/memusage.S29480 "$@"
/usr/bin/memusage: line 265: 29484 Floating point exception(core dumped) $memusagestat $memusagestat_args "$datafile" "$png"
Expected results:
my_name@my_host /tmp % memusage --png=out.png -x 800 -y 300 ./perltest.pl
