Thinking of finally switching from SC7.5 to DMC++... In the meantime can anyone tell me why pointer = new char[size]; compiles without problem in SC but produces error '?_P(unsigned, char *, int)' when compiled in exactly the same context with DMC++. Secondly the IDDE compiler setting 'enable new[] delete[] overloading' seems to toggle itself to 'off' during compilation even when it has been set to 'on'. Thanks for any suggestions Richard

Thanks for the response Walter.
I've seen the same error before and given up on it. The present
occurence appears in a DIB handling class that I 'lifted' and was
originally written in VC, I believe. Not sure how much code you need -
there's more if you want it - just the offending function for now.

Thanks again Walter. The current version of the problem I'm having
appears in an SDI project I'm working on and I'd like to stay in
context. The code below produces the error when dropped as a class into
a framework SDI project in DMC++ but compiles normally in SC7.5. I've
come across the same error when trying to compile parts of 'Numerical
Recipes in C++' - presumably when the compiler hits one of its
allocation routines. Hope I'm not missing something....
All the best
Richard
