asan false positives caused by dlcose #19

Closed GoogleCodeExporter closed 9 years ago

1. application dlopens foo.so
2. asan registers all globals from foo.so
3. application closes foo.so
4. application mmaps some memory to the location where foo.so was before
5. application starts using this mmaped memory, but asan still thinks there are 
globals. 
6. BOOM

I'll create a unit test and then a fix.
