[translation:ERROR] Exception: 'no_release_gil' function can release the GIL: <function assemble_loop at 0x0000000070d4d2e0>
assemble_loop() is marked as no_release_gil because things can get subtly wrong if it releases the GIL in the middle of making machine code and another thread reaches assemble_loop() too. For debugging output, use debug_print(). If you really want to write a custom file, then you need to define and use the C functions open(), write() and close() in a way that calling them won't release the GIL. Alternatively, you can remove @rgc.no_release_gil on assemble_loop() and hope that the crashes you get are very rare. Or, stick everything on the AsmInfo() instance returned by assemble_loop(), and dump that info later. A bientôt, Armin.
