Hi,

In the end I didn't really want to maintain my own Boost fork, so I came up with another solution.

The fundamental problem was that the host application, which I have no control over, was unloading my plug-in before the thread had a chance to call the pthread TSS destructor. When the thread did end, a jump to invalid memory would result.

My workaround is to ensure that the plug-in's code is never actually deallocated. I do this by finding the path of the dynamic library and re-loading it myself. Since the library is already in memory, all this does is increment its reference count by one. When the host application later unloads the plug-in, the reference count is decremented but remains non-zero.

Admittedly, it's a hack and platform-specific, but for my specific needs it works. This may be one option for people who run into similar problems.

Glad to see that you have found a workaround as at present I don't have a fix. Best, Vicente
