Re: [Crash] Various betas with optimization

I get reproducable crashes with various betas (21.0-b57,
21.0-prelim,
21.2-b2) and optimization. The strange things is that these errors
which are reported as
Pid 5479 killed due to trashed stack.
Pid 5479 was killed due to failure in writing the signal context.

Are there any related problems known so far?
Not that I'm aware of. Do you have stack traces with line numbers?
BTW, any reason why --error-checking=all doesn't work with
configure
anymore?
No. I just did three builds with --error-checking=all a few moments
ago. How is it breaking for you?
