Comment (by gk):

 I spent some time on this issue and here is what I have so far:

 If I exclude `servo` from `gkrust_features` I don't see the bug after
 rebuilding `libgkrust.a` 50 times twice on two different machines.

 However, just building `servo` (and the necessary `bindgen`) is hitting
 the problem and early-ish.

 FTR: I've modified `gkrust_features` like so:
 {{{
 -RustLibrary('gkrust', gkrust_features)
 +RustLibrary('gkrust', ['bindgen', 'quantum_render', 'cubeb-remoting',
 'moz_memory', 'moz_places', 'gecko_profiler'])
 }}}
 {{{
 -RUST_TEST_FEATURES = gkrust_features
 +RUST_TEST_FEATURES = ['bindgen', 'quantum_render', 'cubeb-remoting',
 'moz_memory', 'moz_places', 'gecko_profiler']
 }}}

 While that's no resurrection of #26475 my gut tells me LTO might still be
 involved somehow. So, I am testing next disabling LTO and checking whether
 that changes things.
