Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:

The output being present does not necessarily mean that the compilation failed, in fact often it will still return 0 and produce a working binary despite the output, but often it does not, frequently enough that it's impossible to build large rust packages. See the attached log for an example of a real build which fails partway through (despite the fact that all compilation lines emit the traceback).
See Bugzilla for the full thread and attached rust build log.
The reporter (Cc'ed) confirms that this regression occurs on all rust toolchain
distributions (both from the distro and from rustup (maybe?)).
Anyway, I'm adding it to regzbot:
#regzbot introduced: 8ee0b41898fa26 https://bugzilla.kernel.org/show_bug.cgi?id=217923
Thanks.

Fix is now in mainline (thx Palmer!). Contains a Fixes tag, so will most
likely end up in the the next or the next but one 6.5.y release; if not,
please speak up.
#regzbot fix: 14a270bfab7ab1c4b605c01eeca5557447ad5a2b
#regzbot ignore-activity
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
