If you have Perl use the system's default malloc() calls, then you can get sloppy and use Perl's configured free() on stuff that some library malloc()d or pass Perl-malloc()d buffers to an external library that expects to be able to free() or realloc() the buffer.
So some xchat hacker got sloppy and didn't keep straight what needed to be Perl-allocated and what needed to be OS-allocated.
