Compiler crash on a particular action call

[jafingerhut]

Attempting to compile the P4_16 program in the attached file causes a crash in the compiler, one that does not occur if the call to the action foo2() is commented out. The action call looks like it should be legal to me -- is it? Even if not, a compiler crash seems a bit severe.

This is an important question that the spec should settle: can we call actions from a parser directly?
It looks reasonable - especially since we don't have any other kinds of user-defined functions.
I will file a bug with the spec too.

I've verified that after the commits made to fix the crash, the compiler no longer crashes when compiling the sample test program I gave. Closing this issue.
