As said in my intial posting, using base cc causes the same error.
Except when I remove -O2 - then both, ccache and base-cc works. And since
the error is in the generated asm code I'm not sure how anything in 
/usr/obj would affect this.... It seems to be just gcc's optimizer which 
creates invalid ASM code here... for whatever reason.
