Hi Everyone, About a week ago, Apple released XCode 9.3. @chdiza reported a crash bug viewing a message in the pager, when compiling both master and 1.9.4 with the new release of XCode. The issue is at https://gitlab.com/muttmua/mutt/issues/20
The stack trace showed this is from a __stack_chk_fail() check, indicating some kind of stack overflow in or around display_line(). Unfortunately I don't have access to a Mac, and have been unable to duplicate the problem with recent gcc and clang versions on Debian testing, even after adding various flags (e.g. -D_FORTIFY_SOURCE=2 -fstack-protector-all -fsanitize=undefined). I've seen some nice articles such as <https://access.redhat.com/blogs/766093/posts/1976073> on debugging stack protection failures, but obviously need to reproduce the problem to make use of them. If any of you have access to XCode 9.3 and/or would be willing to help me investigate, I would greatly appreciate it. Thank you. -- Kevin J.
