Do you have any more information on your Jenkins job (what it does
differently than a plain run of `make test l=ecl` and how to reproduce
the failure)?

I can't reproduce this, for me the tests run fine without being thrown
in the debugger. I only get two harmlessly looking test failures
(test-program.script and test-require.script).

Well if you don't have a C compiler installed, ECL can not compile
anything unless you run `(ext:install-bytecodes-compiler)`. However,
asdf already contains a test target for the bytecodes compiler with
`make test l=ecl_bytecodes` (which will unfortunately fail at the moment
unless you apply the fix at
https://gitlab.com/embeddable-common-lisp/ecl/merge_requests/118).
