[Tinycc-devel] Segment fault with invalid array initialization

[Zhuo Zhang]

Hi,


Following code triggers a segment fault on tinycc mob 
(5201312cb242ea943848fcf864adacc44d3d190f) on ubuntu 18.04 x86-64.

It seems that the bug is introduced by 
355897a9203661b5f54dbb634294a66ceef17ae6, without considering the size of a.

$ cat test.c
extern int a;
int a[] = {};

$ ./tcc -c -o tcc.o test.c
[1]    41230 segmentation fault (core dumped)  ./tcc -c -o tcc.o test.c
