Your problem is very unlikely to be in the generated C code and just a logical
bug. (Of course that's just a very educated guess though.)
Your question is easily answered when you consider that compiler flags are
orthogonal, so `-d:release --debugger:native` works. Or `--checks:off
--lineDir:off --debugger:native`.
`nim.cfg` contains this:
@if release or quick:
obj_checks:off
field_checks:off
range_checks:off
bound_checks:off
overflow_checks:off
assertions:off
stacktrace:off
linetrace:off
debugger:off
line_dir:off
dead_code_elim:on
@end
@if release:
opt:speed
@end
Knowing this, you can also use `-d:quick --debugger:native`.
