Some details about your operating system and delphi/bcb versions may
help. It probably wont help much but you never know.

I've just been through some very painful stuff in Delphi6 and Win2K
Pro relating to realloc_mem (whether called directly or via dynamic
arrays). The code worked perfectly under Delphi5 but caused AVs when
compiled under Delphi6. I never did solve the problem, just allocated
a single large buffer and avoided realloc.

Obviously not the same as your problem - but highlights the need to be
explicit about what you are using as it can have a big impact on
whether anyone else will be able to reproduce the same problem.
