Content
I found an unused i386 box with OpenBSD and Linux (so no VM): A C program with tan(1.5707963267948961) is wrong on both systems. fdlibm (directly from netlib.org) is correct on both systems. Both OS versions are relatively old, so I cannot file an upstream issue. I was planning to dig through the fdlibm code if there was an issue, but it produces the correct results.
