Hi, in aclocal.m4 (and thus also configure), the test for BASH_STRUCT_WEXITSTATUS_OFFSET contains
/* crack s */ for (i = 0; i < (sizeof(s) - 8); i++) Shouldnt this be /* crack s */ for (i = 0; i < (sizeof(s) * 8); i++) (* instead of -), see attached trivial patch? The minus sign makes no sense at all since even on x86-64 sizeof(int)=4 ... [I found this when tracking down weird behaviour in a highly experimental riscv32 / glibc / qemu chroot, where s=10240 ... that's a different bug in another moving piece though...] Best, Andreas -- Andreas K.
