cc 5.85: Reading anonyomous struct/union members sometimes returns the wrong value
| Reported by: | Jeffrey Lee (213) | Severity: | Major |
| Part: | RISC OS: C/C++ toolchain | Release: | |
| Milestone: | Status | Open |
Details by Jeffrey Lee (213):
The attached code produces incorrect output (5 0, 5 5). The situation that triggers the bug seems to depend on a number of conditions; if you make any of the following changes then the correct output will be produced:
1. Rearrange the struct definition (swap the #if 1 to #if 0)
2. Make the structs & unions non-anonymous
3. Replace the void * members with ints
