--- Comment #2 from Quang Linh LE <ql.le at hotmail dot com> --- Actually the problem was because I recompiled vanilla versions of GCC/GDB on Fedora (I was on Fedora 17 with GCC 4.7). Fedora has long history of patches for GBD include VLA. After trying serveral times with Archer and other VLA implement, I gave up. The best way I can suggest to a normal user is grabbing a new version of Fedora with recent version of GCC and GDB... Unfortunately, if one is on OS X, I can't find any solution atm.
