--- Comment #1 from mikulas at artax dot karlin.mff.cuni.cz 2012-03-29 18:25:43 UTC --- I couldn't attach the file, so I placed in on http://jikos.cz/~mikulas/gcc-crash-files.tar.bz2 . Download the archive, change CC in the Makefile to point to your gcc-4.7.0 PA-RISC binary and run make. This will reproduce the gcc crash.
