I have a very wierd problem. In a big project, stopping in a
breakpoint always works. But, if I simply set to store the session
info in a lps file, then step into stops working =( with this error:

It is the same with Lazarus 1.0.4 + fpc 2.6.2 and also Lazarus SVN + fpc 2.6.2
Windows XP 32 bits
Very wierd ... I already checked the diff between the lpi where step
into/over works with the one that is broken and really, only the
session info storage differs =/
Deleting the lps file didn't help.
Very strange indeed. If it is the session then I have no Idea. Except:
Use a logfile for the IDE, and check, if fpc is called with identical
arguments.
Also check the diff between debug logfiles:

About the error (8 digit address, so you are on win32?):
Cannot insert breakpoint,can happen with positive or negative numbers.
- positive: A user set breakpoint
- negative gdb internal breakpoint (used for stepping)
GDB predicted all possible points where the step can end. And one is in
memory that gdb can not set a breakpoint.
The address suggests (if normal mem layout applies), that this is inside
a dll (system dll). So that would explain why it cant set a breakpoint
there.
That can happen, if the dll is executed in a 2nd thread. E.g. the file
open/close dialogs, start several system threads.
But how that goes with the session ...? No idea.

This may help:
http://wiki.lazarus.freepascal.org/GDB_Debugger_Tips#gdb.exe_has_stopped_working
go to the debugger options
<http://wiki.lazarus.freepascal.org/IDE_Window:_Debugger_Options> and
in the field "debugger_startup_options" enter:
--eval-command="set auto-solib-add off"
