--- Comment #4 from Alexander Monakov <amonakov at gcc dot gnu.org> 2010-11-17 15:29:33 UTC --- (In reply to comment #2) > Only occurs for -fPIC on x86_64-apple-darwin10. Adding -fno-PIC on darwin > suppresses the ICE. Is that in relation to bootstrap flags? There's no PIC flags in the original report. The breakage is rather curious. Build-with-CXX should not cause code generation differences. Can you please build normally-bootstrapped compiler from the same source, build the testcase with the two compilers appending -fdump-tree-all -fdump-rtl-all and attach the two series of dumps?
