Hi,

after long time I'm trying to improve FCL interbase.pp unit. I've new sources of 1.1 compiler downloaded, and I found some strange error in ibase60 unit, I think. In every call to isc_start_transaction() program crashes on access violation error. It's the same even in testib60 program from ibase package, testib40 and ibase40 suite works fine. Tested on RH linux 6.2 on interbase 6.0 and firebird 0.95, both superserver arch.

When I've tried to copy declaration of isc_start_transaction() from ibase40 to ibase60 unit, everything worked fine, so I want think that's a solution... What do you think about it?

The isc_transaction call is one of the few calls that actually changed between version 4/5 and 6, so simply copying it may not be a good idea.

Hi,

It's not good idea definitely, huh... In this case values in XSQLDA are not recognized correctly. What is really cool is that the same units works in 1.0.x compiled programs correctly. Maybe it's compiler problem?

It is possible. One of the compiler people should .

function XSQLDA_LENGTH(n: Integer): Integer;
begin
   Result := SizeOf(XSQLDA) + (n - 1) * SizeOf(XSQLVAR);
end;

sizeof(XSQLDA) is evaluated as 172 by 1.0.5 and 170 by 1.1. If you don't count any possible alignment padding, the size is 170. However, since the unit is compiled with {$packrecords c}, there may a bug regarding that in the compiler. Peter?
