... I take it back, I couldn't locally reproduce this with the
arm-none-eabi toolchain I have around and 12-14 applied in a local
branch.  Hans, last time I saw this error (last night even) there was a
bit more in the log about which file/function was doing the mis-match.
Do you have the full error log handy?  Thanks!
