This happens because os::large_page_size() returns 0, since its not setup in os_bsd.cpp

if (UseLargePages && !UseParallelGC) {
      // in presence of large pages we have to make sure that our
      // alignment is large page aware
      alignment = lcm(os::large_page_size(), alignment); // CRASH here
JDK-7191817 fixed this in hs25. If this should be fixed in hs24 it should be a backport of the fix for JDK-7191817.

This has already been fixed in hs25, so targeting it against hs25 doesn't make sense.

Triaged. 25. (Very low priority)

In hs25 large pages support for OSX was turned off. Maybe we should just backport that fix?
