1517076 - On Windows, Some Rust allocation stacks in DMD bail out before reaching anything useful

Status: NEW

(Core :: XPCOM, defect)

Description

[Bobby Holley (:bholley)]

Attachment: dmd log

STR:
(1) Do an --enable-optimize --enable-dmd build on windows
(2) enable WR if the hardware isn't pre-qualified
(3) save the DMD report
(4) process it

I get something like the attached log. The top two items don't have usable stacks.

I'm going to try with an unoptimized build to see if things are better.

(Though actually this build was also --enable-debug-rust, so I doubt it'll help).

This is probably going to be an issue with whatever XPCOM stackwalker that DMD uses rather than something in DMD per se. 4MB of mystery stacks doesn't sound too bad in the grand scheme of things.
