Do you want an example? http://bugs.freepascal.org/view.php?id=21529 If yes, then the fpc makefiles include -O2 and you need to cancel that. Because -O2 -O1 is still -O2, but -O2 -O-1 (or the long version -O2 -O- -O1) is -O1 Cool. Thank for this tip. In any case, that affects if you can inspect variables in the RTL. It does not seem to be related to the original issue Mind: rtl with debug info, will step into every ansistring_dec/inc_ref and similar. That can be highly annoying Yeah, I know... =) but I just put a new breakpoint in somewhere and press F9 to pass. But: rtl with debug info also allows to access some global vars (like the local time-date-format setting var) Whatever you do: -g defaults to stabs I recommend to not mix stabs and dwarf (it may work, but I do not know). So use the same for LCL, packages and app Maybe best to be explicit -gs -gw -godwarfsets -dwarf allows some properties (those directly mapped to a field) -stabs (and modern gdb) can do -gp (preserve the case of symbols, instead of getting the all caps stuff. I have NOT got a full list of diffs... OK, I'll play with this. Thank you very much.

I cced to lazarus. We should move the discussion On 21/03/2012 14:54, Marcos Douglas wrote: Oh my... =) There are many differences, many options to choice.

At the moment, I think Lazarus ships 7.3.2 http://svn.freepascal.org/svn/lazarus/binaries So far I have no plans to update to 7.4 until either: - I find some existing problem solved in it - I start supporting new features However, my tests so far, have not shown any problems when using 7.4. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
