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?
