Description Richard Horbach CLA 2011-11-02 09:31:16 EDT 
When running C/C++ Code Analysis (RMB > Run C/C++ Code Analysis) on a project containing an assembly file, then a Null Pointer Exception is thrown.

Comment 2 Richard Horbach CLA 2011-11-02 09:36:13 EDT 
n CoreModel.isValidTranslationUnit it is tested if a file is a translation unit. The test result depends on the contentType. Types cheader, csource, cxxheader, cxxsource and asmsource (org.eclipse.cdt.core.asmSource) are valid translation units according to this test.

In org.eclipse.cdt.internal.core.model.TranslationUnit, method getAST an ASTTranslationUnit is created from the file contents. For an assembly file this fails and returns null, resulting in the NPE. 

The bug is that C/C++ Code Analysis tries to process assembly files.

Photran (the Fortran frontend) uses also CDT and I got this bug also.

And as it looks like Fortran files ...

Looks like this issue was recently fixed in bug 431026.
