IAR MSP430 compiler internal error while compiling

Question

IAR C/C++ Compiler for MSP430 5.10.1 [Evaluation] (5.10.1.20144)

I get an illegal state internal error when attempting to compile the FreeRTOS 5.4 Task.c file (everything else compiles fine)

Internal Error: [CoreUtil/General]: Illegal state

The kick start version of IAR (MSP430 version) works fine.

Any thoughts?

Solution

You should try posting this on the Yahoo hosted MSP430 group. Anders, the guy that wrote/maintains the compiler, is good at answering problems there. There are also some very active members there who provide good answers to sensible questions.

You could also send a problem report through their support system. They have always been very good at getting me fixes to any problems.

OTHER TIPS

A few ideas

  • try changing the optimisation level

  • do a "divide and conquer" on the problem source file until you have reduced it to the smallest amount of code that can cause the ICE, then try re-expressing this part of the code to get rid of the ICE and/or send it to IAR as a bug report

  • check for updates from IAR - this may be a compiler bug that they are aware of and maybe even have a fix/workaround for
