Such questions should be asked in fb-devel list.

After quick look at ibase40.pp i found that it defines ISC_STATUS as Long. There should be sizeof(ISC_STATUS) = sizeof(Pointer), i.e. ISC_STATUS should be 4-byte on 32-bit and 8-byte on 64-bit.
I don't know what is Long in FreePascal but guess it is always defined as 4-byte integer, correct ?

Also look at ibase60.inc:

Type
...
ISC_STATUS = clong; // wrong for x64
ISC_INT64 = clonglong;
