When testing Python 3.7.0b5 x64 (and betas before) on Windows 10, I occasionally get segfaults when passing a program as string on the command line. The shortest command to reproduce this on my system is `python.exe -c 1` with heap detection turned on but that might not be reproducible on other systems.It turns out there is a buffer over-read when copying the `PyOS_optarg` string in `main.c`. The attached patch fixes the segfault on my system. | |||
