Created an attachment (id=4485)
 --> (http://llvm.org/bugs/attachment.cgi?id=4485)
reduction: foo.cpp

The attached code fails to compile with g++:

foo.cpp: In function ‘void foo()’:
foo.cpp:4: error: variable or field ‘a’ declared void
foo.cpp:4: error: expected unqualified-id before ‘++’ token

But does compile with clang++:

foo.cpp:4:10: warning: expression result unused [-Wunused-value]
    void(a),++a;
