Format('%s.%.3d', ['name', 1]); This assigns 'name.001' to the pointer

You have to manually call finalize() on the records inside that memory
block prior to freeing them via freemem/reallocmem. dispose on the other
hand will finalize the freed memory automatically.

It was an
ansistring indeed, and finalize did the trick! Thanks for your help. How
does New and Dispose work btw? Do they use RTTI to call finalize
appropriatly? I tried searching the New and Dispose implementations in
the RTL sources, but I just could not find them. What unit are they in?
