--- 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. ohsumit@mothra:~> g++ --version g++ (GCC) 4.7.0 20111115 (experimental) Copyright (C) 2011 Free Software Foundation, Inc.
