Hi all,

I'm writing an application which uses Firebird embedded. My setup is currently Lazarus 1.2.6 with FPC 2.6.4, but I have the 1.4 RC3 files to install if anybody thinks that should make a difference. I'm using the AMD64 version of Lazarus and Debian 7.6 multihome, with i386 architecture also installed.

My problem is a simple one to describe - the program compiles correctly, but the moment I try to do anything with the objects in the data module, I get an immediate 'external SIGSEGV'. When I say do anything with them, this is as simple as adding a line of SQL to a query.

The program compiles OK, of course, and removing gdb from the mix and recompiling just gives me the same error, but now the ASM window pops up at a different address.

Any help gratefully received, because I don't know what else to try...

Brian.
