[PATCH v4 1/3] MSVC: fix t0040-parse-options crash

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On 64-bit MSVC, pointers are 64 bit but `long` is only 32.
Thus, casting string to `unsigned long`, which is redundand on other
platforms, throws away important bits and when later cast to `intptr_t`
results in corrupt pointer.

This patch fixes test-parse-options by replacing harming cast with
correct one.
