I second this; of course the build should ideally be made using the -g debug option. Another suggestion is to build using a flag which generate an error rather than a warning for implicit function declarations (which is more prone to segfaults on amd64 because the default implicit type in C remains "int", 32-bit, but a pointer now requires 64-bit). The source of such a bug is usually simply a missing function prototype or headerfile include. With GCC, building with -Werror=implicit-function-declaration in CFLAGS should help to detect this. However, if the issue is in boehm-gc, gmp, libffi and the ones supplied with ECL are not used, building ECL alone with this flag is only of limited utility (same with -g for debug symbols). -- Matt ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
