26.1.50; Floating point exceptions during byte-compilation on alpha-unknown-linux-gnu |

Another regression on alpha-unknown-linux-gnu, byte-compilation of the
following four lisp files fails with floating point exceptions:
make[2]: Entering directory '/space/homedirs/ulm/emacs/lisp'

The exceptions are triggered in functions string_to_number in lread.c
and float_to_string in print.c when values of infinity or NaN are
being passed.
The same lisp files (from the emacs-26 branch) can be compiled with
Emacs 25.3, though.
(On first glance, it doesn't look like the code in lread.c and print.c
has changed, so the problem must be somewhere else. Signal handling?)
