New submission from Christian Heimes <li...@cheimes.de>:
The zoneinfo C extension has the "freefunc m_free" function with signature
"static void module_free(void)". The signature of freefunc is "void
(*freefunc)(void *)". It takes a void * argument, but module_free() does not.
The signature mismatch is not a problem for most C compilers. But Web Assembly
is more strict. wasm32-emscripten fails and aborts at runtime:
worker.js onmessage() captured an uncaught exception: RuntimeError: function
signature mismatch
Pthread 0x8a1df0 sent an error! undefined:undefined: function signature mismatch
/python-wasm/cpython/builddir/node/python.js:158
throw ex;
^
