Re: [Gc] "GC_is_visble_test failed" error on MS-W indows

 Hi Eli,

The config you sent corresponds to single-threaded one (GC_WIN32_THREAD is not defined) - I checked it with MinGW:
gcc -I include -DHAVE_CONFIG_H tests/test.c extra/gc.c

So, I don't understand why you say it uses Win32 threads.

If you pass --disable-threads to the configure script, the
built library does not use any threading API and does not have any support threads in the client app.

If your app uses pthreads but GC is not supporting pthreads (in case of MnGW, GC_WIN32_PTHREADS not defined) then garbage collection will malfunction.

Regards,
Ivan
