This is a bug report for perl from vincent@vinc17.org,
generated with the help of perlbug 1.35 running under perl v5.8.8.
-----------------------------------------------------------------
[Please enter your report here]
The following script causes a segmentation fault:
#!/usr/bin/env perl
use strict;
use I18N::Langinfo qw(langinfo CODESET);
my $encoding = langinfo CODESET;
print "Encoding: $encoding\n";
my $agrave = chr(0xe0);
my $str = "A grave = '$agrave'";
print "Test 1\n";
print STDERR " print: $str\n";
print "Test 2\n";
warn " warn: $str\n";
binmode STDERR, ":encoding($encoding)";
print "Test 3\n";
print STDERR " print: $str\n";
print "Test 4\n";
warn " warn: $str\n";
$ ./warntest
Encoding: ISO-8859-1
Test 1
print: A grave = 'à'
Test 2
warn: A grave = 'à'
Test 3
print: A grave = 'à'
Test 4
zsh: segmentation fault (core dumped) ./warntest
The backtrace:
(gdb) bt
#0 0xb7e6effc in _int_malloc () from /lib/i686/cmov/libc.so.6
#1 0xb7e70d0e in malloc () from /lib/i686/cmov/libc.so.6
#2 0x080ac83f in Perl_safesysmalloc ()
#3 0x080cae8c in Perl_sv_grow ()
#4 0x080cafa3 in Perl_newSV ()
#5 0xb7ba6fd3 in ?? () from /usr/lib/perl/5.8/auto/Encode/Encode.so
#6 0x0814e008 in ?? ()
#7 0x00000401 in ?? ()
#8 0x00000000 in ?? ()
There seems to be something wrong with the backtrace. With 5.8.7,
there was an infinite recursion, as shown by:
