A (non-public) bug has already been filed on it.

It takes about 2GB or more of memory in the static analyzer to analyze dissect_parlay(); is the static analyzer built 
64-bit or 32-bit, or is it running out of swap space+memory?

Perhaps if the CORBA-IDL-to-Wireshark-dissector tool didn't generate 3MB of source code, this would be less of a 
problem.  (The lights dim when packet-parlay.c is compiled....)

I've been fixing those whilst trying to build with clang.

That reminds me - I need to file a bug asking for some way to turn unknown -f flags into errors rather than warnings, 
so AC_WIRESHARK_GCC_CFLAGS_CHECK will leave that one out with clang, rather than provoking tons of clang warnings.
