If -fwrapv isn’t enabled (whereas with gcc this is the default with ‑O2), then it means -ftrapv is enabled. And from the manual page : This option generates traps for signed overflow on addition, subtraction, multiplication operations. Did you checked if the binary compiles fines with all ‑O2/‑O3 options replaced with ‑O0 in configure/Makefiles along gcc ?
