Yes, this is likely. Basically, all these changes are only needed for the lazy macros which are created in Buffer.cpp:3229. There is even a FIXME comment by Abdel asking why a full macro is not used. After reading the code a bit I have to admit that it is quite confusing. Also other parts of the macro machinery ignore the constness concept where ever needed. Georg
