I have considered that as well, but it seems a bit awkward to split
tests into two modules just because some of them for success and some of
them for failure. That said, even if I were to split them into two
modules, I'd still want a programmatic interface that allows me to set
this in the C++ sources. I'm using automake's `check` infra-structure
and specifying command-line arguments or environment variables on a per
module basis is a pain.

I tried this but without any effect. Either alternative below in the
fixture's constructor yields the same result.
The results I'm getting for tests for the coreutils `false` and `true`
utilities look like:
Running 2 test cases...
Entering test suite "src::core"
Entering test case "test_false"
unknown location(0): fatal error in "test_false": child has exited; pid: 12822; uid: 1000; exit value: 1
process.hh(117): last checkpoint: Running: false
Leaving test case "test_false"
Entering test case "test_true"
core.cc(40): info: check run ("true", 0) passed
Leaving test case "test_true"
Leaving test suite "src::core"
Looks like something is catching and acting upon system errors before
unit_test_monitor gets a chance to do so. I think this happens in
execution_monitor::catch_signals() but am not sure.
Any hints would be appreciated. FTR, still using the Debian package for
