I think you are misinterpreting what is causing the core.
Creating a drawing area of size 5000x5000 should cause
no trouble. 

However, I'm guessing your program also tries to create
a pixmap of that size, forcing the server to allocate
something like 50M of data. (Depending on your colordepth)

X fails to allocate that much memory and returns a 
BadAlloc error.

To find out exactly what is causing the error, you could
run the program under a debugger with the --sync option.
