WebCALL pushes a return address on the stack - in your case, it pushes addr_8.So your func_print actually gets addr_8 as a string to print, and str_0 pointer value as a size in bytes. So it prints a lot of bytes, until it hits an unassigned page. PUSH str_0 only pushes bottom 32-bits of an address (sign-extended to 64-bits).

So it produces the error segment fault or abnormal program termination at runtime. Example: C C++ #include #include int main (void) { int* p = malloc(8); *p = 100; free(p); *p = 110; return 0; } Output: two way locks for gates
