cc 5.85: Designated initialisers incorrectly initialise anonymous unions
| Reported by: | Jeffrey Lee (213) | Severity: | Major |
| Part: | RISC OS: C/C++ toolchain | Release: | |
| Milestone: | Status | Open |
Details by Jeffrey Lee (213):
Using designated initialisers to initialise a struct containing anonyomous unions results in the values being written to the wrong location. The equivalent code using named unions appears to work OK (see attached code).

Note: attempting to initialise the .y or .b members of v results in an internal compiler error.
