https://community.intel.com/t5/Software-Archive/Internal-error-backend-signals/m-p/1006976#M32510 <P>I'm programming on MIC recently, but I have met a disappointing problem. When I use icpc to compile my program, I find it spews an error, which is "Internal error, backend signals". Unfortunately, there are no more clues. So I want to know how can I do to correct this error, how it happens, and the possible reasons to this error. I use OpenMP and C++, and the execute mode is offload. &nbsp;Thanks!</P> Mon, 05 May 2014 03:29:29 GMT ding_e_ 2014-05-05T03:29:29Z https://community.intel.com/t5/Software-Archive/Internal-error-backend-signals/m-p/1006976#M32510 <P>I'm programming on MIC recently, but I have met a disappointing problem.

There is not one particular cause for this sort of error and to fix and find a work around requires our seeing the code and reproducing the error. The backend internal error could related to an optimization or code generation. It is a guess, but you might be able to avoid the error by dropping the optimization to -O1 or -O0.</P> <P>Can you provide us with the code that causes the error?</P> Mon, 05 May 2014 08:03:53 GMT https://community.intel.com/t5/Software-Archive/Internal-error-backend-signals/m-p/1006977#M32511 Kevin_D_Intel 2014-05-05T08:03:53Z
