Perl: 5.8.0 (32-bit binary from www.sunfreeware.com)
Gcc: 3.2.1
When I try to use a compiled module:
#!/usr/local/bin/perl
use Date::Calc qw(Delta_Days);
I get a segmentation fault, truss gives:
open("/usr/local/lib/perl5/site_perl/5.8.0/sun4-solaris/auto/Date/Calc/Calc.so",

Module was compiled using "-mcpu=v7 -m32" gcc flags to compile 32-bit,
since my perl is 32-bit. (If I compile it 64-bit I get the ELFCLASS64
error.) I've also tried compiling 32-bit using gcc 2.95.3 as I'm
painfully aware how broken gcc 3.x+ is, same results. Is this just
a broken perl?
Sorry for posting a perl issue, didn't get much help from those lists
and I REALLY need to get this resolved soon.
