I've not yet looked into converting the procedure call parameters into a record. However, using gdb I got the following backtrace: gdb flocate break fpc_raiseexception =>gives Cannot access memory at address 0xc800 run c:\windows\system32 => passing the directory for flocate to search in. ... snip a lot of my program's debug output...
