Description of problem:
After the recent update to gcc-4.1.2-13.fc6, I observe many ICEs on C files produced by MLton (http://mlton.org), a compiler for Standard ML that uses C and gcc as one backend.  The ICEs occur with optimization level 1 or higher; I do not observe the ICEs with optimization level 0.  I did not observe any such ICEs (with any optimization level) with 
gcc-4.1.1-51.fc6.

As the C code is machine generated, it isn't particularly human readable.
Nonetheless, I've attached a preprocessed source file, as indicated by the gcc error message.

Version-Release number of selected component (if applicable):
gcc-4.1.2-13.fc6

How reproducible:
Always


Steps to Reproduce:
1. gcc -c -O1 ccVnl11d.out.c


Actual Results:
z.2.c: In function ‘Chunk2’:
z.2.c:1188: warning: assignment makes pointer from integer without a cast
z.2.c:1533: warning: assignment makes pointer from integer without a cast
z.2.c:1552: warning: assignment makes pointer from integer without a cast
z.2.c:164: internal compiler error: Segmentation fault
