Hello, James!

I found an error at GetMem / ReAllocMem: Your code:

  getMem(tmpStrings, 100);
  {reAllocMem(tmpStrings, (I + 1));}

reserves 100 or (I + 1) BYTES, but you need space for 100 or (I + 1) 
STRINGS, i. e. the code should be:

  getMem(tmpStrings, SizeOf(String) * 100);
  {reAllocMem(tmpStrings, SizeOf(String) * (I + 1));}

Even then, I don't know if fpc behaves correctly converning deallocation when 
<String> defaults to <AnsiString>. Maybe somebody else can respond to this?

Another note: Please replace tabulators by spaces when posting code.

Hope this Helps.

Anton Tichawa.
