I see segmentation fault for Text-CSV_XS-0.52 but have not determined why. This is perl v5.8.4 built for i386-linux-thread-multi on Debian sarge with kernel 2.4.27-3-686-smp. Not all classes of error produce the segfault. Below is code which produces the segfault. #!/usr/bin/perl -Tw use Text::CSV_XS 0.52; my $csv = new Text::CSV_XS; open my $file, "<&*DATA" or die "Can't open: $!"; while(my $row = $csv->getline($file)){} $csv->error_diag; #segfault here __DATA__ """

perl5.10 is better, and gives me a good hint where to look: $ perl -T test.pl sv_upgrade from type 8 down to type 6 at test.pl line 7, <$file> line 1. Thanks for the short and concise test case

In trying to reproduce the fail on my current development state, I found that I already fixed this specific problem in July. If you're in a hurry, get it from git://repo.or.cz/Text-CSV_XS.git I'll release 0.53 soon. Probably even today
