gallium state tracker calls calloc for 0 sizes arrays ?
...f (proginfo->Parameters) {
t->constants = (struct ureg_src *)
calloc(proginfo->Parameters->NumParameters, sizeof(t->constants[0]));
And if I protect the code against that one, another one at 5618:
t->immediates = (struct ureg_src *)
calloc(program->num_immediates, sizeof(struct ureg_src));
With the regular glibc malloc these both succeed as it actually
returns a valid memory address (posix says it may also return NULL)
I believe that the fragment program in question comes from:
src/mesa/main/state.c update_program() and then from the
else if (ctx-&g...
