Bug ID: 117531 Summary: Miscompile with -O2 and -O0/1/3 Product: gcc Version: 15.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: yunboni at smail dot nju.edu.cn Target Milestone: --- When I compiled this code with -O2, it triggered SIGKILL. With -O0/1/3, it returned 0: ```c int a; unsigned b; char c = 228; int f(int g) { int d = g ? g - 1 : 1, e = 113 - d; return e & 65535; } void h() { for (; f(c + 115) + b > 40;) for (;;) ; } int main() { h(); } ``` Details can be found here: https://godbolt.org/z/fjG69eqoq
