Hmmm...

If ASAN does not come first, libjsig comes first, and libjsig uses malloc, it will use the malloc implementation from the C-Runtime, not the one ASAN interposes. That, in turn, could cause weird errors or crashes when later memory is freed at a place where ASAN interposition of malloc holds, since we use a different free(). 

I would probably just disable the libjsig tests for ASAN completely.
