There are two options in gcc which can formally be used simultaneously: *–fsanitize=address enables Sanitized build *–ftest-coverage -fprofile-arcs (or just –coverage) enables Test/Code Coverage build One possible practical purpose of such mixing is to reduce the number of builds (which can be quite time consuming). But the question is: can we really mix these two builds? Can each of them impact the behavior/results of another one making a difference from a separate build? Any ideas/experience? Thanks in advance.
