Code should be compiled in debug mode for coverage tests
100%
Description
Based on https://gcc.gnu.org/onlinedocs/gcc/Gcov-Intro.html#Gcov-Intro, for code coverage we should use debug mode compilation. Right now, testing is done using the optimized mode.

- Category changed from Integration Tests to Build
Category shall be Build. "Tests" category refers to integration tests.
We should choose between
- let
--with-coverageimply--debug, or - raise an error if
--with-coverageis enabled but--debugis disabled

I prefer the first approach: let --with-coverage imply --debug

Unfortunately, I'm not seeing a clean way to implement note-2 approach. During configure stage, code coverage module is loaded after default compiler flags, making it impossible to update conf.options.debug in coverage.
Loading coverage early has an implication of forcing all configuration tests to be run with code coverage flags, which is not really desirable.
The dirty way is to combine coverage and default-compiler-flags into one, but I don't want to go this direction. At least not right now.

Could code-coverage tool detect the value of conf.options.debug?
It should raise an error when code-coverage is enabled but debug is disabled.

Yeah. Detection is possible. I'll make an update.
