Hi there,
"internal compiler error" would suggest the compiler is faulty, and a compiler upgrade could fix it.

But from past experience, it could also be memory related, you could try a

make -j1

to force using only one thread to minimize memory usage. It might also be some hardware memory issue, compiling is doing a good job in stressing memory :)

Good luck!

[James Turner]

Good point, it's worth running a memory tester to check this, since non-repeatable or inconsistent compiler errors do occasionaly indicate an unreliable system.

[Gijs]

As this report was issued two years ago and may have been an unreliable system, I'll close it. Please report back if you can still reproduce it with current next.
