Line 1314 in 2310acd

ImVec2* circlePos = (ImVec2*)alloca(sizeof(ImVec2) * (circleMul * halfCircleSegmentCount + 1));

Blaming the line looks like it was modified 4 years ago last, so its odd that it is just complaining now about it since I've been using the lib for quite some time, just recently formatted and setup a new machine and now it is complaining about it.
I am on Win11 using VS 2022 cpp20.

Did a quick scan and changing it to _malloca seems to be the way to go based on the usage somwhere else and the define at the beginning of the file.

This sucks and there is no standard replacement for that. I guess it needs heap allocation :(
