--- Comment #2 from mlg <mlg7 at yandex dot ru> 2011-03-01 11:34:30 UTC --- Yes it _is_ hard to detect. My colleague was suspecting a build system bug/feature at first (hours for a full rebuild). If it was a direct call, there would be a linker error. >If the call was direct to func instead, >it would be better. Unfortunately or fortunately, refactoring a huge real world application to make bugs easier for the compiler to detect is not an option.
