[This is based on the branch 'dev/wl/build-fixes'.]

The log file `snippet-names-c5b165525229969dd268a5b19f9f64fd.log`
contains

```
GNU LilyPond 2.25.14 (running Guile 3.0)

```

AFAIK, signal 6 is 'SIGABRT'.

Note that the files `lilypond-multi-run-*.log` all contain

  thread_suspend failed

which seems to be a hint that we have a problem with thread support on
macOS (Carl runs on macOS Sonoma which identifies itself as Darwin
23.2 on arm64e).

Any idea how to tackle this?  BTW, `make doc` without `CPU_COUNT=10`
succeeds on his computer.
