LLVM ERROR: Cannot yet select: 0x2625340: f64 = ConstantFP<3.540000e+02> :What is it?

I get this message once in a while and llvm exits the program.
What might be the cause ?

llvm version: svn
host: Linux x86_64

Hi Gabi,

this error means that the backend can't handle that f64 constant for
some reason. Which target are you trying to compile for?

Regards,
Christoph
