[Octave-bug-tracker] [bug #37308] JIT build fails some numerical tests; non-JIT build is OK.

[Arun Giridhar]

Follow-up Comment #5, bug #37308 (project octave):

Apparently the second half of my comment# 4 got eaten, so here it is:

Valgrind result for rand.cc:

This may account for the observed crash in cellfun.cc:

  libinterp/corefcn/cellfun.cc ...........................==11732==

==11732==    at 0x4EE4188:

$OCTAVESRCDIR/octave/build/libinterp/.libs/liboctinterp.so.1.0.1)
==11732== 
 PASS  122/122 


I will update when valgrind is done.
