Short of fully reading and understanding the recently added patch to glibc I can only guess that previously somehow the fpu environment was reset or initialized between the faulty sin() and the actual cos() call. IOW worked by coincidence. Pretty much x87 specific. The correct fix is to fix the testsuite of python-cffi like upstream did. Back to Matej. Nevertheless to satisfy curiosity it would be interesting to know what glibc did before to prevent this issue. -- You are receiving this mail because: You are on the CC list for the bug.
