[libcxx-commits] [libcxx] [libc++][filesystem] Increase error message buffer size to prevent truncation (PR #203531)

[Sean Perry via libcxx-commits]

This function has code to grow the buffer if it isn't big enough.  Should the call to vsnprintf, when the buffer is being resized, make a copy of ap just like the first call to vsnprintf?
