Previously, the number of command line args was not checked for cygwin process. Due to this, segmentation fault was caused if too many command line args are specified. https://cygwin.com/pipermail/cygwin/2023-August/254333.html Since char *argv[argc + 1] is placed on the stack in dll_crt0_1(), STATUS_STACK_OVERFLOW occurs if the stack does not have enough space. With this patch, char *argv[] is placed in heap instead of stack and ARG_MAX is increased from 32000 to 2097152 which is default value of Linux. The argument length is also compared with ARG_MAX and spawnve() returns E2BIG if it is too long.
