Bug#330521: different results for different parameters order

[Michal Čihař <michal@cihar.com>]

Package: gcc-4.0
Version: 4.0.1-9
Severity: normal

Hi

while compiling with different parameters order you get different
results:

$ gcc -g -L/usr/X11R6/lib/ -lGL -lglut -lGLU -pthread -Wall configure.c -o configure.bin 
configure.c: In function ‘main’:
configure.c:11: warning: assignment discards qualifiers from pointer target type
$ ./configure.bin 
$ gcc -g configure.c -L/usr/X11R6/lib/ -lGL -lglut -lGLU -pthread -Wall -o configure.bin 
configure.c: In function ‘main’:
configure.c:11: warning: assignment discards qualifiers from pointer target type
$ ./configure.bin 
Segmentation fault

Note that only source filename has moved from end to beginning and
program runs differently (segfault is a code problem). This is taken
from configure of Raydium engine [1], problematic file attached to bug
report.

1. http://raydium.cqfd-corp.org/

Preprocessed files (*.i) and assembly (*.s) are same in both cases, 
only difference is how collect2 is called, once (in failing case)
resulting object is before GL libs, second time after then. But order 
should not matter, or am I wrong?

I hope I provided enough information.
