I will apply (something close to) this patch, since it's no big deal, but I don't understand why it's needed. According to the POSIX spec, the gl_offs field is never used unless the GLOB_DOOFFS flag is provided to the glob() function, which GNU make never does. And looking at the glob.c version we provide as part of GNU make, the access to this field is always protected by a check for GLOB_DOOFFS as far as I can see. Also if I force the make version of glob.c to be used in my testing I don't get any failures. The only way I can see this being a problem is if (a) I misread something in make's glob.c, or (b) there's some local version of GNU libc glob installed on one of your systems that has a bug related to gl_offs usage, and GNU make is choosing that instead. _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
