1652650 - Build failure with deterministic js shells

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect, P1)

Description

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

Attachment: stack

This command seems to fail for me:

AR=ar sh ./configure --enable-debug --enable-more-deterministic --with-ccache --enable-gczeal --enable-debug-symbols --disable-tests

See the build failure stack.

The first bad revision is:

summary:     Bug 1640844 - Part 4: Only used smoothed growth factor for recent collections r=sfink

Jon/Steve, is bug 1640844 a likely regressor?

Using clang 9 and GCC 9.3.0, also fails on m-c tip rev 3dfec4ecf5a5.

Sorry! Yes I broke this. I'm a bit surprised we don't have a a build with --enable-more-detmerministic on infra though. Don't fuzzing builds have this?

I don't know fuzzing build plans. I'm community / external now. I know we have an existing bug 1031339 for this.

Perhaps :truber or :decoder would have a better answer for you?

[Christian Holler (:decoder)]

Our fuzzing builds currently don't use it and I think adding another build for this to CI is currently not an option as we are trying to reduce the amount of builds used. If I remember correctly, this build doesn't break often, so maybe we can just get off with fixing it when it breaks.
