alt Hacker News> In 2001 Mark Probst implemented tail-call optimization in GCC
MSVC didn't add tail-call optimisation until sometime in the 2010s, IIRC.
I distinctly remember sending a tail-recursive C++ program to someone who developed on Windows, and it crashing, in the late mid-to-late 2000s.
MSVC stands for MicroSoft Visual C++ compiler AFAIK.
It famously doesn’t support a few features of C99.
They don’t really seem to care much about regular C support (non-C++).
