Unit tests fail with profile=debug

[rleh]

I accidentally discovered that the unit tests on Nucleo-F767ZI work in profile=release mode, but not with profile=debug.

Steps to reproduce:

cd modm/
cd test/
make compile-nucleo-f767zi
cd ../build/generated-unittest/nucleo-f767zi/
scons profile=debug -j16 program

First the resumable_test:354 fails and later an assertion fails in the timeout_test:
