--- Comment #1 from Martin Storsjö martin@martin.st --- For extra context; this reproduces with llvm-mingw https://github.com/mstorsjo/llvm-mingw/releases/tag/20231128. With older mingw-w64 releases, calls to exp2() go to mingw-w64-crt's internal implementation, but when targeting UCRT, with the latest few releases, the exp2() calls go to the UCRT exp2() function.
