Bug ID: 68038 Summary: "Internal compiler error: Killed: program cc1" should read "Virtual memory exhausted" Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: driver Assignee: unassigned at gcc dot gnu.org Reporter: zackw at panix dot com Target Milestone: --- 99+% of the time, when the compiler proper dies on signal 9, it's because we're on Linux and the out-of-memory killer has killed the compiler proper because it ate all available RAM. But the error message you get when this happens *sounds* like there's a bug in GCC. I suggest the driver be changed to special-case SIGKILL and print a different message, along the lines of gcc: compilation process (cc1) killed by SIGKILL This almost always means your computer does not have enough RAM to compile this program. Try adding swap space or reducing the number of concurrent compile jobs.
