New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
Currently building Python 3.9 on Windows produce many compiler warnings. 3.8 and master are clean. * Warnings in the _sre module caused by the bug in MSVC (complains about automatic conversion of "void **" to "const void *"). Fixed by backporting PR20508. * Warnings in many files related to using legacy C API (e.g. PyUnicode_AsUnicode) in Windows specific code. * ..\Objects\exceptions.c(2313): warning C4098: 'MemoryError_dealloc': 'void' function returning a value * ..\Objects\frameobject.c(400): warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data The last two may be hidden bugs. ---------- components: Extension Modules, Interpreter Core messages: 388731 nosy: serhiy.storchaka priority: normal severity: normal status: open title: Compiler warnings in building Python 3.9 on Windows versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43499> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
