Bug#488563: [powerpc] Optimisation results in wrong code

Package: gcc-4.3 Version: 4.3.1-2 Severity: serious When using the following (somewhat contrived code): -- #include #include #include #include void misc (uint8_t **header) { uint8_t *h; h = malloc(8); *((uint64_t *) h) = (uint64_t) 0; *((uint32_t *) h) = (uint32_t) 0x;
