And +there is nothing to do but fix the GCC bug. + +However, if that GCC bug really only affects exception handling and nothing +else, given that the PPL only uses exceptions for error reporting, we can +probably say that the PPL works on the Alpha *apart* from error reporting. +In other words, under this hypothesis (which we have no way to check), +users that are not interested in catching exceptions thrown by the PPL +(in response to invalid arguments, heap exhaustion, overflows, ...) +should probably not worry. Your mileage may vary...
