In our code base (restraint), we patch and recompile the m4 code base. https://github.com/tar-mirror/gnu-m4 In their code, they have the following which fails to compile when SIGSTKSZ < 16384 is interpreted. This is going to be a challenge to make work.
# define SIGSTKSZ 8192 #ifndef SIGSTKSZ # define SIGSTKSZ 16384 #elif HAVE_LIBSIGSEGV && SIGSTKSZ < 16384 /* libsigsegv 2.6 through 2.8 have a bug where some architectures use more than the Linux default of an 8k alternate stack when deciding if a fault was caused by stack overflow. */ # undef SIGSTKSZ # define SIGSTKSZ 16384 #endif On Wed, Mar 3, 2021 at 3:05 PM Florian Weimer <fwei...@redhat.com> wrote: > * Carol Bouchard: > > > Thank you Daniel and Richard.
