A weak part of DPScan is that it uses various libraries which simply
malloc memory (or use other C library functions). That memory has to
come from the fixed amount between the top of the program and the top of
the wimp slot.
In the old days the temptation was to keep it too low. The program would
go wrong with images that just happened to use up enough of this limited
memory.
Problem is when you use a different compiler, libraries etc the memory
needed changes.
This is one reason why using a dynamic area in addition to the programs
wimp slot can be useful.
Anyway it is now possible to give the program a decent wimp slot.
The endless woe of memory management on RISC OS.
