FB3.0 RC1 Fbclient.dll function calls modify FPU control word
-------------------------------------------------------------

                 Key: CORE-5102
                 URL: http://tracker.firebirdsql.org/browse/CORE-5102
             Project: Firebird Core
          Issue Type: Bug
          Components: API / Client Library
    Affects Versions: 3.0 RC1
         Environment: Windows
            Reporter: michalk1
            Priority: Minor


This is almost similar to CORE-4043, which was fixed in 2.5.3. In FB3 RC1, FPU 
returns with all flags masked, ie:

before call     1 00 11 00 110010  (0x1332)
after call      1 00 11 01 111111  (0x137F)

All remote functions seem to be affected (isc_attach_database, 
isc_dsql_execute2, isc_dsql_fetch, isc_dsql_free_statement, 
isc_commit_transaction, isc_service_start etc.)
