While compiling a recent Linux kernel, I got trunk gcc to say this:
security/keys/dh.c:362:1: internal compiler error: in estimate_node_size_and_ti
me, at ipa-inline-analysis.c:3385
0x9c2c6c estimate_node_size_and_time
../../trunk/gcc/ipa-inline-analysis.c:3385

Flag -O2 required. I'll have a go at reducing the code.
