Between 20240523 (f0a02467bbc35a478eb82f5a8a7e8870827b51fc) and 20240524
(51f4b47c4f4f61fe31a7bd1fa80e08c2438d76a8),
memory use compiling rust with a 32-bit gcc exploded in stage 2, breaking
bootstrap:
cc1plus: out of memory allocating 4084 bytes after a total of 3223085056 bytes
make[3]: *** [/vol/gcc/src/hg/master/local/gcc/rust/Make-lang.in:412:

So far, I've no idea which commit in this range might be responsible. Seems
to call for a reghunt.
