>Description:
The following little test case results in an internal error.
---------------------------------------------------------------------------
struct C
{
  int i;
  static struct C **c;
};


extern int sig_max();

C ** C::c = new C *[sig_max() + 1];

void foo()
{
   C::c[2]->i = 6;
}

/tmp/gcc.C: In function `void __static_initialization_and_destruction_0(int,

/tmp/gcc.C:10: Internal compiler error in find_function_data, at function.c:329
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
---------------------------------------------------------------------------
We found this problem with gcc-3.1 and it happens on all system we tested
(Solaris SPARC/Intel & Linux). It's still there in 3.1.1

>How-To-Repeat:
Just try to compile the above test case.

>Fix:
Workaround: create another static int variable to hold the result of sig_max()
and use that for the array dimension.
