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.
