Created by Torsten Rüger (torsten@ponton-hamburg.de) on Monday, July 13, 1998 4:56:09 AM PDT Additional Details : I'm getting a floating point exception in js/src/jsapi.c line 1184 because the check JSDOUBLE_IS_NaN does not recognise the variable as being Nan 0xfffffffffffff Updated by Mike McCabe (mccabe@netscape.com) on Monday, July 13, 1998 1:18:59 PM PDT Additional Details : Thanks for looking at this; other people have noticed the same problem with builds on alpha linux and bsd - platforms that raise SIGFPE on int casts of NaN values. I have a fix in hand, and it's checked into the javascript sources in js/ref (from which js/src is generated; see READMEs in js/ref and js/src.) The fix is to change JSDOUBLE_IS_INT(d, i) to conditionalize the (jsint) cast on d being non-NaN, plus some removed casts and restructuring. I'm putting off propagating it into js/src for the time being, because the client is currently in a stability freeze for the time being, and it's not a critical fix. I'll close this bug as soon as I can propagate the fixes to js/src, and confirm that they correct the crash.

I propagated the fix, and Torsten Rüger just confirmed it for me on Alpha Linux. Many thanks!
