[Bug c/13475] New: ICE on SIMD variables with partial value initialization

[gandalf at winds dot org]

The following code crashes the GCC 3.3.2 compiler when variable 'a' is
initialized with an incomplete list of values. Normally, the rest of the values
in a structure are assumed to be zeroed if left unspecified. The compiler does
not crash if the {1} below is edited to a {0}. The crash appears to happen
regardless of the -march or -mcpu setting.


typedef int v8qi __attribute__((mode(V8QI)));

int main()
{
  v8qi a={1};
}


Compiling displays the following:

simd.c: In function `main':
simd.c:5: warning: unused variable `a'
simd.c:5: internal compiler error: Segmentation fault
Please submit a full bug report,
