[cfe-dev] idea: feature to force cleanup of freed stack/heap - useful enough?

[Dennis Luehring]

it would be nice to have an clang feature to instrument cleanup freed 
stack/heap space
with an defined bit pattern (0, 0xfff...,) - this way it would be easier 
to find stack/heap missuse

before dtor end(exception chain) the object space will be nulled
before function/method/ctor end(exception chain) stack space will be nulled
before mallocs-free the allocated space is nulled (problematic when 
using other librarys)

i little bit in the area of the addresssanitizer but should be faster, 
but without the auto-detection of missuse

what do you think
