             Bug #: 12817
           Summary: Assertion `NextFieldOffset <= RecordSize && "Size
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

reduced test case (provided by Craig Schroeder)

Running clang trunk on:

struct s1 {long a[-6 / (8 * sizeof (long))];};struct s2 {int b;struct
s1 c;};struct s3 {struct s2 d[1];};struct s3 * e;

results in:

Assertion `NextFieldOffset <= RecordSize && "Size mismatch!"' failed.

FWIW, gcc 4.4.3 accepts this without error or warning.
