I went through most of BAD_FREE reports yesterday and in many cases it was
mmap + munmap with some offset, which coverity doesn't like.
>From what I have read, it should be possible to annotate code to make coverity
stop complaining. For example by adding following:
/* coverity[EVENT_TAG_NAME] */
I'm not exactly clear where to get "event tag names" yet, as these seem to be
different from error names that appear in *.err logs.
Before I dig deeper into this, would anyone be opposed if we start adding
such annotation to LTP source?
