Critical Issue
Description
The C2H Compiler does not support multiple build configurations (for example Release or Debug) in the Nios II IDE. After creating one or more accelerators in a particular configuration, the C2H Compiler produces undefined results if you switch to a different build configurations and create more accelerators.
Resolution
For a specific SOPC Builder system and Nios II IDE project, specify C2H accelerators in only one build configuration. You can use multiple build configurations, as long as only one configuration specifies C2H Compiler settings.
