Bug#691576: [reverse-bisected] GDB stops with SIGTRAP at 0 address fixed with GCC 4.8

2014-07-25 Thread Émeric MASCHINO
Hi, Please have a look at upstream bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61799 I was asked to test GCC 4.8 and found this issue go away with locally-recompiled GCC 4.8.2 (upstream source, as ia64 is no more supported by Debian). Whether this was expected or not, I don't know.
