Bug 65049

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; Win 9x 4.90)

Description of problem:
When using the gcc-3.1 final in current Rawhide (also happened with prior cvs 
version) the compiler dies on main.c with the above internal compiler error.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Get source (http://sexorcisto.net/gdsrc.tar.gz)
2. unpack source
3. make clean
4. make
	

Actual Results:  make[1]: Entering directory `/var/www/html/gdsrc'
gcc -O2 -march=i686 -fomit-frame-pointer -funroll-loops -frerun-loop-opt  -
DWORD_WRAP -DRANDOM -DMALLOC_bibopmalloc     -DMUD_LIB=\"/mud/millenia/lib\" -
DBINDIR=\"/mud/millenia/bin\" -o main.o -c main.c
main.c: In function `main':
main.c:423: Internal compiler error in do_SUBST, at combine.c:439
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla/> for instructions.
make[1]: *** [main.o] Error 1
make[1]: Leaving directory `/var/www/html/gdsrc'
make: *** [driver] Error 2

Expected Results:  Should have compiled without error and moved on.

Additional info:

You may browse the tree as-is via http://sexorcisto.net/gdsrc

You will find the main.c main.s main.i files all there from the original source 
and with the -save-temp cmdline option.

As I mentioned, earlier rawhide gcc 3.1 cvs versions used to work, although not 
the prior one.  Also, gcc296 works without flaws leaving me to believe a recent 
change to gcc is at fault.
