So on cmath.exp, we've seen something like this before, on macOS. What was happening was that the C source contained matching `sin` and `cos` calls, and a compiler optimization replaced that pair of calls with a single call to C's cexp. And then cexp didn't handle the zero signs correctly.
I don't have an issue reference to hand; all this is from (highly fallible) memory. |
