runtime: out-of-memory error is inscrutable #594

I'd like to see a further enhancement to make(): I'd like it to report failure other than with a runtime error. This needn't break backward compatibility other than very minorly, e.g.: var buf []byte var ok os.Error buf, ok = make([]byte, ...) // return with ok != nil on failure buf = make([]byte, ...) // runtime error as currently implemented Providing the make() is presumed to provide two values any time it is used in tuple assignment, existing code like the following would at least get an "assignment count mismatch" compile time error: var buf []byte var s string buf, s = make([]byte, ...), "fubar" file.go: assignment count mismatch: 3 = 2 Or maybe it's not too late an incompatible change; the language still seems at least somewhat in flux. |

on my machine, running the code below gives rise to the following error message: SIGBUS: bus error Faulting address: 0xf1 pc: 0x7af3 throw: malloc/free - deadlock double panic this is not an ideal message when the real problem is probably that it cannot allocate that much memory (mine fails at 1GB) package main import "fmt" func main() { var buf = make([]byte, 1) for { buf = make([]byte, len(buf) * 2) } } darwin 386 b45e8d6389ae tipThe text was updated successfully, but these errors were encountered:
