The root cause is that, even tough we’re passing “-classpath
build/classes:src”, only the first element of the classpath is
searched. If we pass “-classpath foobar:build/classes”, then Main.class
is not found. That suggests another problem with ‘stat’-related
functions.

Hmm -O0 is brute-force. It doesn’t work for me though if I also remove
the ‘remove-call-to-free’ phase, though.
I also tried this Classpath patch:

It seems to have the same effect as my initial patch.
I’m lacking inspiration now!
