icpc version 11.1.046 with -O3 not running.

Hi,

I have a console application that was running fine with the Linux x64 icpc version 11.0.083 using the optimization flag -O3. With version 11.1.046 the code runs when compiled with the debug flag -g, but even though it compiles with -O2 or -O3, the executable hangs without any output. Are you aware of any optimization issues transitioning from 11.0.083 to 11.1.046?

Thanks,

Dave

Surely, you know more about your application than you have let on. If it's a numerical application, do options such as -fp-model source make a difference? Do you have floating point expressions where algebraic shortcuts may break it?

It would be nice if you can share the sample test case to narrow down the issue.
