int32_t a = 1 / ((0 >= a) + (int32_t)4294967295);
This uses `a` before it is initialized.
The divide by zero is random. Sometimes it happens sometimes it does not even.
<source>: In function 'main':
<source>:3:41: warning: 'a' is used uninitialized [-Wuninitialized]
3 | void main() { int32_t a = 1 / ((0 >= a) + (int32_t)4294967295);
printf("%d", a);}
| ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
<source>:3:23: note: 'a' was declared here
3 | void main() { int32_t a = 1 / ((0 >= a) + (int32_t)4294967295);
printf("%d", a);}
