There are several other applications that then optionally use libsigsegv for stack overflow protection (such as m4 and awk), as well as for user-managed page faulting for garbage collection purposes (such as guile). In fact, I'm a bit surprised that emacs rolls its own protection instead of taking advantage of libsigsegv - it might be worth suggesting that to upstream emacs. Upstream libsigsegv comes with a fairly decent testsuite for low-level testing of what types of SIGSEGV handling is possible (regardless of whether that recovery was done by native windows hacks as in the current build, or via sigaltstack which is what I hope will happen when it is reconfigured against the new cygwin). And if those tests aren't enough it is also a fairly simple test case using (32-bit) m4 (when linked against a rebuilt libsigsegv) to do: echo 'define(a,a(a))a' | m4 --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --95oa6ddqnMMG3SMTXC19PfSjl4iw7A4U6 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" Content-length: 604 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJVpYrPAAoJEKeha0olJ0NqaB0H/RP5Tfmn2loe4pOa76Tpa7zT Q0HidwNTXg3ndY31ZE+EEBF0WDLs3L3uoCGaoFV2BHE3FUGbe3TEnO/a5EstFypt INmDqO1TWDI5i53TzeJUENQJwspAQuVKzQROWtuhzqoJirjTBTpdCXTwhqoxTZSX 51gMABtAi09LPE7iwke6z++uHO5cRwv/WSZRpqSDD6hMbJLDetQr22kVI59+SiLA ZFexCudL32Sm8ceka9HNKmf7+jPqpIOH1XFdaMltauSOuOytsHxXng9q8FvkI8CT q/iHOZsrrSHaFrmHCJcepPFe0QWexVU58fIox0aZEzyRzz8RZD/fpvBijSm6l6k= =ijHv -----END PGP SIGNATURE----- --95oa6ddqnMMG3SMTXC19PfSjl4iw7A4U6--
