Default Bug#684635: ICE when compiling malformed struct initializers

Package: gcc-4.7
Version: 4.7.1-6
Severity: minor

The following invalid C code triggers an segmentation fault
in gcc-4.7:

cat > t.c <<'EOF'
struct bla{char **a;};void test(void){struct bla b = {.a =(char**){"a","b"}};}
EOF
gcc -c t.c

results in:
| t.c: In function ‘test’:
| t.c:1:46: warning: initialization from incompatible pointer type [enabled by default]
| t.c:1:46: warning: (near initialization for ‘(anonymous)’) [enabled by default]
| t.c:1:46: warning: excess elements in scalar initializer [enabled by default]
| t.c:1:46: warning: (near initialization for ‘(anonymous)’) [enabled by default]
| t.c:1:50: internal compiler error: Segmentation fault
| Please submit a full bug report,
