Bug ID: 60013 Summary: Build of 176.gcc from CPU2000 loops in cc1 starting with revision 207231 Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other Assignee: unassigned at gcc dot gnu.org Reporter: pthaugen at gcc dot gnu.org CC: bergner at gcc dot gnu.org, dje at gcc dot gnu.org, jakub at gcc dot gnu.org Host: powerpc64-linux Target: powerpc64-linux Build: powerpc64-linux Created attachment 32006 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32006&action=edit preprocessed source Compile of file fold-const.c from 176.gcc in cpu2000 loops starting with r207231. Compile command 'gcc -c -m64 -O2 fold-const.i'. Stopping in debugger (a few different times) gives backtrace like the following.
