Hello.

When starting gdb, I get:

warning: Got an error handling event: "No symbol "VALMASK" in current context.".

Needles to say, any debugging of Lisp objects and Lisp backtrace doesn't work.
It seems clang optimizes away VALMASK even at zero optimizing level.

Can we rearrange this somehow?  External and defined in a C-file?  Or fix .gdbinit to not use VALMASK?

	Jan D.

Hello.

ARRAY_MARK_FLAG is also optimized away.

I took a stab at fixing this in trunk bzr 114691; please give it a try.

A quick test indicates that it is working.
