Compiler: C6000 INTERNAL ERROR

To investigate the cause of this problem, I need a test case which allows me to reproduce that behavior.  Please preprocess the source file with the problem assignment, and attach that to your next post.  Also show all the build options exactly as the compiler sees them.

Thanks and regards,

-George

Hi George,
I have big code base, and when I extract the related code into different project, it did not happened again.
However I can give you the log message :
recipe for target 'blabla.obj' failed.
INTERNAL ERROR:Decomposition Error
This may be a serious problem. Please contact ...

Note also that Visual c++ compiler succesfully comopiles the code.
When I use memcpy() instead of assignment, it also works.

here is the build log and compiler options:

Please preprocess the source file MissionComputerCls.cpp as described here.  Then attach the resulting .pp file to your next post.  It is possible that I cannot reproduce the bug with that file.  But, in my experience, that is very rare.

Thanks and regards,

-George

Thank you submitting a test case.  I can reproduce the problem.  I filed CODEGEN-1996 in the SDOWP system to have this investigated.  You are welcome to follow it with the SDOWP link below in my signature.

Thanks and regards,

-George

could you put the case link?

Please visit this SDOWP link.  Enter the issue identifier (ID) CODEGEN-1996 in the Search box in the upper left corner.

Thanks and regards,
