Source code is gcc trunk: https://codeload.github.com/gcc-mirror/gcc/zip/master Was unconfigured project.
I parsed unconfigured gcc-master on Ubuntu Linux and on Solaris, with GNU and Studio 12.4 tool chains (on both OS) and this exception never repeated. Code analysis shows that the only reason for this NPE to happen is possible another exception in Preprocessor.EvaluateDirectiveExpression before $getPPValue(BitWidth) is called. (That's because $getPPValue(BitWidth) never returns null, as null can never get into EvaluateValueHelper.$PPValues). And that's how it was on Nov 12 when the bug was filed. So the remedy is just to add "if (ResVal != null) { ..." Sputnik bddd002445b7
There is no change for this bug in cnd-main. Seems it was filtered out because binaries-list file was overridden
