[Tinycc-devel] Tinycc fails to assign in global scope

[Thomas Preud'homme]

Greetings everyone,

while trying to compile mksh I encountered the following bug:

% cat global_affect.c 
static int foo;
int *var = &foo;

int main(void)
{
        foo = 0;
        return *var;
}

% tcc -o global_affect global_affect.c 

% ./global_affect 
zsh: segmentation fault  ./global_affect

I might be completely wrong but I have the impression that the problem is that 
when a symbol value is made pointer, its constant value is not set to its 
address. As init_putv assume the symbol value pointed at by vtop has a correct 
constant, it fails.

Best regards,

Thomas Preud'homme
