[Bug c/34732] New: Optimization flag trigger unexpected crash

[ijeukens at yahoo dot com dot br]

This is the core of the problem (at comp_0.c):

...
for(j = 0;j < 3;j++) {
   comp_0_fptr[j][1]();
}
...

     comp_0_fptr holds pointers to void functions. When compiling with -g,
everything works ok. Compiling with -O2, or any other, the effect that I get
is:

   comp_0_fptr[0][1]();
   comp_0_fptr[1][1]();
   comp_0_fptr[1][1]();  

   and not comp_0_fptr[2][1](); at the last statement.
