Ah, so that explains the missing stacktrace. I always compile all the frameworks/components I use with debug information. But I omitted the RTL and FCL code. I guess that is also the reason why Delphi shipts with debug versions of the VCL. :) > I use this script for compiling: Thanks, I'll apply that to my environment. Incidently, I found the bug last night. I forgot to set a compiler define that controls how tiOPF stores Boolean values in a database. By default tiOPF uses a Char(1) (values 'F' or 'T'), but I prefer and always use a ShortInt (values 0 or 1) in my database schema. > In my experience the FPC-gdb combination is more robust with STABS than DWARF > but on 64 bit STABS is not available. I heard that too, but as you noted, only DWARF is available for 64-bit platforms. In recent days I've had renewed interest in my Object Pascal based debugger for FPC. About a week ago I started working on that again (first time in 2 years :-/ ). > When you have a RTL with debuginfo and there still is no usable stack > information try to set breakpoints everywhere where an EVariantError is > raised. I know many IDE's (not just for use with FPC) include things like CPU Register and Assembler windows. So other than looking impressive, how useful are those windows really? Do they actually tell you anything that can help with debugging? Or are they only useful when you optimised say your Object Pascal code with some ASM code blocks.
