[bug report] OMP: Error #13: Assertion failure at kmp_csupport.c(492)

[bug report] OMP: Error #13: Assertion failure at kmp_csupport.c(492)

My ifort-compiled code (which has run successfully many times before now) reported this message during execution:

OMP: Error #13: Assertion failure at kmp_csupport.c(492).
OMP: Hint: Please submit a bug report with this message, compile and run commands used, and machine configuration info including native compiler and operating system versions. Faster response will be obtained by including all program sources. For information on submitting this issue, please see http://www.intel.com/software/products/support/.

Here is the compiler and machine information: ifort (IFORT) 11.1 20100414, x86_64-linux-gnu. My compiling and linking flags are "-fp-model source -openmp -fPIC -xHOST -O3 -ipo -static-intel".

I would prefer not to post the source publicly, but can send it to someone if that would help figure out the problem.

There was at least one other instance of this reported in the past here: http://software.intel.com/en-us/forums/topic/269754. That thread seemingly ended without any obvious resolution/solution.

You said it had been running successfully up to now. Has the source changed? Or anything else environmental that you are aware of?

The 11.1 compiler is dated. You perhaps have reasons for still using that; however, if you can try a newer release, if the cause relates to the compiler or run-time libs, perhaps there is a resolution already available. If you do not have the convenience of trying a newer release, I could do that for you.

You can send me a private forum message with the code and build/execute instructions or if you prefer, submit an Intel Premier Service Request (https://premier.intel.com/) and provide the source and build/execute instructions and request the issue be directed to me.
