The current workaround is to disable pymalloc when Python is built with EXPERIMENTAL_ISOLATED_SUBINTERPRETERS: _PyPreConfig_InitCompatConfig(PyPreConfig config): #ifdef EXPERIMENTAL_ISOLATED_SUBINTERPRETERS / bpo-40512: pymalloc is not compatible with subinterpreters, force usage of libc malloc() which is thread-safe. */ #ifdef Py_DEBUG config->allocator = PYMEM_ALLOCATOR_MALLOC_DEBUG; #else config->allocator = PYMEM_ALLOCATOR_MALLOC; #endif #else ... #endif
