--- Comment #11 from Toshiro K. Ohsumi <ohsumit at molbio dot mgh.harvard.edu> 2011-11-15 15:13:04 UTC ---
When compiling an empty program, but with a large include with many templates,
I note that there is a failure at line 1421 on ipa-inline.c.  However, it seems
only to occur when -O2 or -O3 is set.  (Are these the only times inline
optimizations are performed?)  Unfortunately, I do not have a small test case. 
The includes come out to be about 2M in size.
