The following valid code snippet triggers an ICE since GCC 4.2.0
(when compiled with "g++ -g"):
=============================================
struct A
{
char c[1];
} a;
const int i = (int)&a.c[0] - 1;
=============================================
bug.cc:5: internal compiler error: in loc_descriptor, at dwarf2out.c:9181
Please submit a full bug report, [etc.]
When compiled as C code the snippet compiles fine.
