--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2011-05-03 10:45:43 UTC --- Remarks: * This is clearly a bug; the diagnostics given are simply wrong. * It's not a conformance bug, as C99 permits a limit on object size as small as 64KiB (in a hosted environment) (and the apparent limit here - see <http://gcc.gnu.org/ml/gcc-patches/2011-05/msg00096.html> - is 1EiB). * If it's hard to support such large objects for some reason, a call to sorry () is the appropriate way to diagnose the lack of support instead of incorrect overflow diagnostics. There would still be a bug, since GNU programs should avoid arbitrary limits (meaning anything smaller than that imposed by the target instruction set, C semantics, ABI etc.), but a less serious one (GCC is full of inappropriate arbitrary limits, such as 2GB for a string constant, but the only ones people seem to encounter in practice are those from stack overflow).
