Bug #60566 for Catalyst-Plugin-Alarm: malloc() errors using Catalyst::Plugin::Alarm

Howdy, I recently tried to use Catalyst::Plugin::Alarm to set a global timeout in my application. Nothing fancy, I just started out by adding the plugin and configuring it with: alarm => { global => 30 } Unfortunately, I end up with errors like this: perl-fcgi(770) malloc: *** error for object 0x107008b60: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug After some experimentation, it looks like Sys::SigAction is causing problems on my platform (Mac OS X, Perl 5.12.1 installed from MacPorts). As an experiment, I tried altering it to use the "if ($WIN32)" code that sets $SIG{ALRM} instead, and the problem went away. While I'm not qualified to debug the problem with Sys::SigAction, people on IRC seem to feel that it's potentially unsafe. Maybe you could add a config option to allow people with this problem to use the $SIG{ALRM} path instead? Anyway, thanks for the module. Hopefully this information will be of some use.
