Running gmtime("NaN"); in void or scalar context causes a segmentation fault

   [0]suppy@luna:~$ perl -e'gmtime("NaN")'
   Segmentation fault
   [139]suppy@luna:~$ perl -e'$foo = gmtime("NaN")'
   Segmentation fault
   [139]suppy@luna:~$ perl -e'@foo = gmtime("NaN")'
   [0]suppy@luna:~$


This appears to happen on all released perls since 5.12 (inclusive):

   [0]suppy@luna:~$ for perl in ~/perl5/perlbrew/perls/perl-*/bin/perl;
do $perl -v | grep "This is perl"; $perl -e'gmtime("NaN")'; echo "^ -
$? #########"; done
