If you link an application with your own malloc functions, cygwinb19.dll 
will forget about internal functions and will call your ones. You have to 
provide 4 functions - malloc, free, realloc and calloc. For example, 
cygwin-compiled Xemacs doesn't use cygwin's malloc, but provides its own 
malloc.
