Notes
(0050900) montrezorro (reporter) 2011-08-17 13:49	Compiling at 32bit: seems there are no problem.

(0065959) Reinier Olislagers (developer) 2013-03-01 09:48 edited on: 2013-04-02 05:06	Attached a test program. Unless OP has a test program that demonstrates the issue or somebody else has more information on this, I propose this issue be closed, because the test program correctly generates an EIBDatabaseError for client/server Firebird. ==================================================== Edit: removed info about embedded Firebird; it doesn't match the bug report. ==================================================== 1. FPC trunk x86 r23675: properly returns a DoInternalConnect exception: An unhandled exception occurred at $0042E29D: EIBDatabaseError: : DoInternalConnect : -Unable to complete network request to host "doesnotexist.example.com". -Failed to establish a connection. $0042E29D $0042F5F3 $0042EC7B $004432AE 2. FPC trunk ppcrossx64 r23675: An unhandled exception occurred at $000000010003AAFC: EIBDatabaseError: : DoInternalConnect : -Unable to complete network request to host "doesnotexist.example.com". -Failed to establish a connection. $000000010003AAFC
