The Bugbug bot thinks this bug should belong to the 'Firefox Build System::General' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I'm not able to reproduce this on my Fedora 34 64-bit machine.
Are you working outside the sysroot? Can you share your:

• mozconfig, if you have one
• $objdir/config.status?

Also, are you able to reproduce the failure on:

• central/29d6504debf5b2028a9da65026ae86a06b5a655d
• On a clean build (e.g.: after a ./mach clobber)?

We should add bug 1717151 in the CLOBBER file

Julien just had the same issue

Bug 1717151 moved AddDefaultReturnStatements.cpp from gfx/angle/checkout/src/compiler/translator/tree_ops to gfx/angle/checkout/src/compiler/translator/tree_ops/d3d, and the build system doesn't handle file moves when they're referenced from the same moz.build.

A manual clobber works around the problem.

1. I executed $ ./mach build and the build failed as expected. mozconfig and config.status attached.
2. $ ./mach clobber
3. $ ./mach build succeeded

Set release status flags based on info from the regressing bug 1717151
