Please post your emerge info. This seems related to bug 52533 (mcopidl crashing in both cases)...
I've been seeing the same type of problem (*** glibc detected *** double free or corruption (!prev): 0x00000000005487b0 ***) with my system after a gcc/glibc update and it turns out I had gcc 3.3 and gcc 3.4 mixed in the environment. You need to verify which one you are going to use and make sure all of your kde/qt related builds are against that compiler/library set.
