Hi,
Using the call to:
_configthreadlocale(_ENABLE_PER_THREAD_LOCALE);
at the start of the Live555 engine thread fixed the issue detailed in
this thread.
Thanks,
Richard.

Hi Jonathon/Ross,
Thanks for the info Jonathon, humbly missed this, I suspect the heap
corruption throw me whilst performing the tests.
For it's worth, using the libraries for client sink, setlocale is the
only call which fails in a multi-threaded environment on a current
Windows 10 platform.
I've two options, modify the code to add a lock, which I do not want
to do, or understand the consequences of defining LOCALE_NOT_USED.
As a final note on this email chain, can you tell me what those
considerations may be if setlocale is not called?
What issues may we run into as a client or server endpoint using the
libraries not calling this function?
Appreciated,
Richard.

Thanks for the info. Although we can try to make our code safe to run in
multiple threads, there’s not a lot we can do if an underlying language runtime
library or OS call is not thread safe.
Another reason to avoid threads, if possible.
