In triage, this looks AIX-specific to us in that it's the system linker failing to open a file. It might be our fault the file's not there, but it's unclear. It could also be a builder issue, possibly.

[bcmills]

FWIW, the C toolchain on the aix builder may be deficient in some other ways too; see #56896.

Did this only fail once?

From what I found, exit status 12 means out of memory, so it is similar in that respect to the other AIX failures that have happened lately.

Some new tests or other changes to the compiler or runtime have probably caused binaries to be larger. Maybe they were close to the limit before and now go over in some circumstances.
