Subject SIGILL, illegal instruction on httpd startup
Date Wed, 13 Jun 2012 02:50:17 GMT
Hello, I'm getting a SIGILL, illegal instruction each time I startup my
application that is running fine on several other environments. It takes
place in startup.pl, before any error_log output is generated. I'm
including the back trace below in hopes that someone has a suggestion for
me, as I'm quite new to debugging Mod Perl internals.  If anyone has any
suggestions on what might be the cause or suggest some next steps to
diagnose I would be greatly appreciated.  -- Thank you.

The particulars of the environment are the following:

CentOS 6.2 64Bit
Perl Version 5.12.4   (also occurs with 5.14.1)
Mod Perl Version: mod_perl-2.0.5
Apache Version: httpd-2.2.19


Backtrace:
Program received signal SIGILL, Illegal instruction.
