The offending code is this (From gcc-4.1.1/gcc/opts.c):
1293 const char *help, *opt, *tab;
1294 static char *printed;
1295
1296 if (flag == CL_COMMON || flag == CL_TARGET)
1297 {
1298 filter = flag;
1299 if (!printed)
1300 printed = xmalloc (cl_options_count);
1301 memset (printed, 0, cl_options_count);
1302 }
=> the SEGFAULT occurs in memset.
Could it be, "static char* printed" should be initialized = 0?
I.e. static char* printed = 0;
