--- Comment #43 from thopre01 at gcc dot gnu.org --- Thanks. In the stage before the one that fails, could you add -fdump-tree-all-details -fdump-rtl-all-details to the command line when compiling that jcf-parse.c file and send me an archive with all the generated files? Another archive with trunk + Richard Biener's patch might help but given the time to bootstrap gcc on SPARC I'll try to find the problem only with the broken gcc and will come back at you if I need more. Best regards.
