Edited Unassigned: vld.cpp(unmapBlock) crashes in CriticalSectionLocker cs(m_heapMapLock); [10573]

I have posted an issue about using vld in a program with an external dll injected.
(See https://vld.codeplex.com/workitem/10572)

There is again another issue happening when a program with an external dll injected.

When the program terminates, it crashes.

There are two cases depening on the availability of the external dll's source code.

[case 1] external dll's source available
Adding the following line into the external dll's source file will solve this issue. I don't know why, though.

include <vld.h>
But, isn't there any way to avoid this issue without adding vld.h to the external dll's source file?

[case 2] external dll's source not available
How can this issue be resolved?

Overall, vld does not terminate gracefully when a program is injected with an external dll.
