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)​:
