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.
