Sadly, buggy programs are not guaranteed to fail. Somewhere in your program is a bug and you need to find it. For example, maybe a pointer has a bad value, but you are using it to store something. This overwrites something that it shouldn't. When you staticly link the program, you may be stepping on something that you don't need. But generate position independent code, and now you're clobbering something important.

The good news is that you have found a way to reliably expose the bug. The next step is to remove the bug.
The illegal operation sounds like you nailed a return address on the stack.

And yes this sort of thing happens to me a lot, although it's usually a program that works on hp but not sun (or vice versa). And it's always a bug a in my code. For this reason, I try my program on both systems as a quality check.

dh_bugfiles

DH_BUGFILES(1)							     Debhelper							    DH_BUGFILES(1)

NAME

       dh_bugfiles - install bug reporting customization files into package build directories

SYNOPSIS

       dh_bugfiles [-A] [debhelperoptions]

DESCRIPTION

       dh_bugfiles is a debhelper program that is responsible for installing bug reporting customization files (bug scripts and/or bug control
       files and/or presubj files) into package build directories.

FILES

       debian/package.bug-script
	   This is the script to be run by the bug reporting program for generating a bug report template. This file is installed as
	   usr/share/bug/package in the package build directory if no other types of bug reporting customization files are going to be installed
	   for the package in question. Otherwise, this file is installed as usr/share/bug/package/script. Finally, the installed script is given
	   execute permissions.

       debian/package.bug-control
	   It is the bug control file containing some directions for the bug reporting tool. This file is installed as
	   usr/share/bug/package/control in the package build directory.

       debian/package.bug-presubj
	   The contents of this file are displayed to the user by the bug reporting tool before allowing the user to write a bug report on the
	   package to the Debian Bug Tracking System. This file is installed as usr/share/bug/package/presubj in the package build directory.

OPTIONS

       -A, --all
	   Install debian/bug-* files to ALL packages acted on when respective debian/package.bug-* files do not exist. Normally, debian/bug-*
	   will be installed to the first package only.

SEE ALSO
