--- Comment #4 from Ian Lance Taylor <ian at airs dot com> --- There don't seem to be any sparc64-linux machines in the GCC compile farm, so I can't recreate this myself. Are you able to recreate the problem while running under gdb? A backtrace from the point of the signal might help. The stack backtraces you included unfortunately don't tell me anything useful. Thanks.
