Description viric 2012-01-12 16:02:01 UTC 
Version:           3.7.0
OS:                Linux

Debugging code with some dlopen() and dlclose(), if there is some reference to an address of the dlopen()ed code (function pointer, data, etc..) referenced *after* a dlclose(), valgrind simply says that the address is totally unknown to him (not stack, not heap, ...).

valgrind knew, before dlclose(), what address was that. It would be nice if valgrind could report that the address may reference a dlclose()d shared object.

Reproducible: Always



Expected Results:  
It would be nice if valgrind could report that the address may reference a dlclose()d shared object.
