--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Note that it's only glibc's job to ensure that longjmp doesn't change the
mask - that is, that when setjmp returns for the second time, the
floating-point environment is the same as it was on entry to longjmp. If
it's the kernel or processor changing the mask on entry to a signal
handler, that's not glibc's problem.
