            Bug ID: 115213
           Summary: [15 regression] Excessive memory use compiling rust
                    with 32-bit gcc
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---
              Host: i386-pc-solaris2.11, sparc-sun-solaris2.11,
                    i686-pc-linux-gnu
            Target: i386-pc-solaris2.11, sparc-sun-solaris2.11,
                    i686-pc-linux-gnu
             Build: i386-pc-solaris2.11, sparc-sun-solaris2.11,
                    i686-pc-linux-gnu

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:
rust/rust-ast.o] Error 1
make[3]: *** Waiting for unfinished jobs....

cc1plus: out of memory allocating 65536 bytes after a total of 3011272704 bytes
make[3]: *** [Makefile:1197: rust/rust-session-manager.o] Error 1

cc1plus: out of memory allocating 4064 bytes after a total of 3049021440 bytes 
make[3]: *** [/vol/gcc/src/hg/master/local/gcc/rust/Make-lang.in:422:
rust/rust-macro-expand.o] Error 1

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

I am going to say this is a dup for now.
