#66 nescc built by gcc 4.2.1/LLVM of Mac OS X Lion wouldn't run

[Tadashi G. Takaoka]

The nesC compiler that is built under Mac OS X Lion wouldn't run by "Internal error".
The C compiler of the platform is gcc 4.2.1/LLVM.

What steps will reproduce the problem?
1. Under $TOSROOT/apps/Null

$ make null

What is the expected output? What do you see instead?
Null app should be successfully built.
Observed:

$ make null
mkdir -p build/null
compiling NullAppC to a null binary

Can you elaborate on "Further investigation revealed that ** the aggregated struct assignment fails ** in SIGSEGV." / provide some kind of stack trace ?

(I have no access to a Mac OS X Lion machine)

[Tadashi G. Takaoka]

I cannot get core file from the crash.
Inserting 'printf' to trace the program reveals that the execution stopped at line 217 of types.c

nt->size = nt->alignment = cval_top;
