Package: rustc
Version: 1.79.0+dfsg1-2
X-Debbugs-Cc: mips64el at buildd.debian.org, rust-sequoia-sop at packages.debian.org
Control: affects -1 src:rust-sequoia-sop

Hey mips64el builders--

https://buildd.debian.org/status/fetch.php?pkg=rust-sequoia-sop&arch=mips64el&ver=0.35.0-3&stamp=1721479018&raw=0
shows that rust-sequoia-sop 0.35.0-3 fails to build from source on mips64el.

It builds fine on all the other debian platforms.

I've copied what appear to the the relevant error messages, with a
little bit of context, at the end of this message.

0.35.0-1 build successfully on mips64el -- but there are two significant
differences between the versions:

 - 0.35.0-3 is building one additional binary, "sqopv", which was not
   being built by 0.35.0-1

 - 0.35.0-3 add "-C codegen-units=1" to RUSTFLAGS, in an attempt to
   reduce the size of the sqop and sqopv binaries.

Given that this error is happening in dh_auto_test, before sqopv is
getting built, i tend to think it's the RUSTFLAGS change.

I'm going to try removing the RUSTFLAGS change on mips64el to see
whether it can build successfully, but this suggests that there may be
some platform-specific bugs in rustc that put mips64el at risk.

I welcome any suggestions or pointers for other ways to resolve this!

Thanks for maintaining rustc in debian!
