Re: 21.5 build time segmentation fault
Ar an tríú lá is fiche de mí Iúil, scríobh Mats Lidell:
Hi,
I have received this bug report, https://bugs.gentoo.org/661592, which is about a
segmentation violation during the build process of xemacs 21.5.34. I managed to recreate
the problem once(!) on one of my machines but after that I have not been able to get it
again, sigh, although I have tried it a like 20 times or more.
I can't see that we have had this issue on the build bot either which uses the same
machine I got the error on and does a lot of builds!?
Aidan: Have you seen anything like this? (With a hope that some recent development you
have done has touched and fixed things that could cause segmentation violations in this
old code base!?)
No, nothing convincingly like this. The log file doesn’t show the usual
XEmacs “Fatal error” message.
That’s a *very* new GCC and those are some *very* aggressive optimisation
flags. Were your own crashes with a similar level of optimisation?
NEWGC currently does give segmentation violations on OS X, because (as far
as I can see) the Mach exception handler code is broken, and some of my
recent changes prompted configure to treat OS X as non-POSIX again.
