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.
