Thank you very much for you interest in our Sourcery G++ Toolchains!

Can you describe your host environment? I am unable to reproduce this
error on our test systems using arm-none-linux-gnueabi 2005q3-1 and
2005q3-2 (linux hosted).

The ICE you mention should only be generated when using
-mfloat-abi=softfp. Perhaps you are missing an option in the compile
line?

As a workaround I recommend using software floating point until the
problem is fixed. You can specify this with -mfloat-abi=soft.

This issue will be looked at as soon as possible. Thank you!
