--- Comment #7 from Denis Excoffier <g...@denis-excoffier.org> --- (In reply to Francois-Xavier Coudert from comment #6) There is no lldb here, and also no direct 'bt' available. I used gdb with a break point: % cd /tmp/lcl/tmp/gcc/obj % % grep -n 'gcc_assert (sizeof reg_names == sizeof initial_reg_names)' ../gcc-4.9.2/gcc/reginfo.c 178: fprintf(stderr, "%s:%u %u %u\n", __FILE__, __LINE__, sizeof reg_names, sizeof initial_reg_names); gcc_assert (sizeof reg_names == sizeof initial_reg_names); % % cat test.c /* nothing */ % % /usr/bin/cc --version powerpc-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5493) Copyright (C) 2005 Free Software Foundation, Inc.
