asan false positives caused by dlcose

Originally reported on Google Code with ID 19

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.
