The bug asm.c triggers is that subst_asm_operand doesn't have enough
information to correctly substitute the parameter. It just sees
r==VT_LVAL and generates "xorl (%eax),(%eax)" although the constraint
is "r".

This is unrelated to your problem.

Your problem is that tcc doesn't know what ".lcomm" is.

Instead of

        .lcomm X, Y

try

        .bss
X:
        .space Y

Don't forget to switch back to the correct section.
