-// Regression test for
-// http://code.google.com/p/address-sanitizer/issues/detail?id=19
-// Bug description:
-// 1. application dlopens foo.so
-// 2. asan registers all globals from foo.so
-// 3. application dlcloses 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
-
-// This sublte test assumes that after a foo.so is dlclose-d
-// we can mmap the region of memory that has been occupied by the library.
-// It works on i368/x86_64 Linux, but not necessary anywhere else.
-// REQUIRES: x86_64-supported-target,i386-supported-target
