--- Comment #21 from Gary Mills <gary_mills at fastmail dot fm> --- Most of the words in the title are wrong now. I'm attempting to build gcc-7 now. The ICE occurs on both SPARC and x86 systems. It only happens with the native assembler. The result is a structure that contains many NULL pointers, which cause a segmentation violation when xgcc dereferences one of the NULL pointers. I've been attempting to find the origin of this structure by examining the source, without success. Can someone show me a debugging technique that will reveal the origin of this structure?
