--- Comment #3 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-12-05 03:46:59 UTC --- I suspect that for the FSF gcc build, the static libasan library has identical code to that in the dynamic libasan but compiled as a static library. FSF gcc wouldn't know to do any tricks like building the dynamic libasan with mac function imposition code and static libasan with mach_override code. I am still unclear if the mac function imposition method itself requires a shared library to be used for the libasan code. If that is in fact the case, we likely won't have functional static libasan support on darwin since mach_override will eventually be deprecated, no?
