--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-12-19 19:53:43 UTC --- Created attachment 26146 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26146 gcc47-pr48306.patch Not sure if this case is something we need to slow the driver down for, but if yes, this completely untested patch should do that. I've also fixed a problem where we IMHO can overflow the alloca returned buffer on cygwin or wherever HOST_EXECUTABLE_SUFFIX is used, though have no access to such a system to test that.
