Subject: [PATCH] Port alternate signal stack to upcoming glibc 2.34
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* src/sysdep.c (sigsegv_stack): Increase size to 64 KiB and align
it to max_align_t. This copies from Gnulib???s c-stack.c, and works
around a portability bug in draft glibc 2.34, which no longer
defines SIGSTKSZ when _GNU_SOURCE is defined.
