GDB output for the failing call

On Ubuntu 16.04 x86_64 with multiarch setup (amd64 + i386), the call to
fesetenv() from an i386 program causes a segfault in
sysdeps/i386/fpu/fesetenv.c:116.
As far as I can tell, this line has been introduced with bug 16068. The
installed glibc version is libc6:i386 2.23-0ubuntu3.

GDB output including locals, registers and backtrace is attached. A more
detailed description of the environment that leads to this issue can be found
