Why does the WolframKernel exit on OS X without a trace during Integrate?

A notebook or .m file with the input would be more useful in terms of diagnosing the issue.

Thanks Mr. Lichtblau. Next Monday I can upload an OS X panic file I sent to Apple if that helps catching the bug.

Should not be an option for the user to disable all TimeConstrained, especially if the user expecting an Integrate that lasts for hours or even overnight ?

Variations of that have been discussed in past but never implemented.Perhaps just as well, since many integrals with parameters, and even some without, would just wander off to Never-never Land. I should add that this is more or less incidental to the crash issue, which is just a bug (at least if the cause is what I suspect and described).

Might be a kernel problem involving a failure to properly deal with the result of an internal interrupt. Integrate uses TimeConstrained in many places to avoid hanging when e.g. trying to sort out provisos (conditions for which one has convergence, or a result might hold), attempting to take limits, etc.
