I'm not sure that would really help in this case. The fact that x86 and x86-64 are both clean with structural alias analysis would seem to show that there is no fundamental bad interaction between it and Ada anymore. We cannot really debug on PowerPC 64-bit so I'd suggest to disable Ada in your builds for the time being (unless you have the time to investigate yourself). Maybe the problem will arise on other platforms and we'll be able to debug it. -- Eric Botcazou
