I've been looking for this segfault for a while. This may be related to my last post about the double requests under mod_perl because if I use a cgi-script instead of a mod_perl handler I don't get the segfault. But there's an issue with mod_rewrite, too. I have a url that can go to an advanced search page: http://localhost/search/advanced/extra/path Everything after /search is extra path info. I thought it would be nice to make it easy to use: http://localhost/advanced/extra/path So, I was using this rewrite rule: RewriteRule ^/(foo|bar|advanced)(.*) /search/$1$2 But that's causing a segfault. My guess is that /search/advanced/extra/path ends up with a subrequest of /advanced/extra/path And the rewrite_log shows that happening. Interesting, is that although this causes the segfaults RewriteRule ^/(foo|bar|advanced)(.*) /search/$1$2 this works fine: RewriteRule ^/(advanced)(.*) /search/$1$2 Looks like a bug in mod_rewrite, too. Here's the httpd.conf: <VirtualHost *:9000> RewriteEngine on RewriteLogLevel 9 RewriteLog rewrite_log RewriteRule ^/(foo|bar|advanced)(.*) /search/$1$2 <perl> package My::Hello; use strict; use Apache::Constants qw( OK ); sub handler { my $r = shift; $r->send_http_header('text/plain'); $r->print('hello'); return OK; } </perl> <Location /search> Allow from all SetHandler perl-script PerlHandler My::Hello PerlSendHeader on </Location> </VirtualHost> And here's the backtrace: Program received signal SIGSEGV, Segmentation fault. 0x4012c65c in memset (dstpp=0x0, c=0, len=3355583254) at ../sysdeps/i386/memset.c:64 64 ../sysdeps/i386/memset.c: No such file or directory.
