Probably I did not explain the problem clearly.

The problem is that user code in foo.dll allocates no TLS
explicitly. But amount of using TLS increase.

gcc generates a call of __get_eh_context() in foo(), and it
allocates TLS by TlsAlloc().  But it seems no one releases the
TLS.  Neither foo.dll nor mingwm10.dll imports TlsFree().
Probably there is a bug in libgcc or mingwm10.dll.
