Lazarus 2.2 or 2.3 ?
In 2.3 some work has been started to debug into dll...
Is there a way to reproduce this?
Also try:
lazarus.exe --debug-log=c:\logfile.txt
--debug-enable=DBG_EVENTS,DBG_VERBOSE,DBG_WARNINGS,DBG_ERRORS,DBG_VERBOSE_BRKPOINT,DBG_STATE,DBG_COMMAND_ECHO,DBG_DATA_MONITORS,DBG_LOCATION_INFO,DBG_BREAKPOINTS,DBG_FPDEBUG_VERBOSE,FPDBG_BREAKPOINT_ERRORS,FPDBG_BREAKPOINTS,FPDBG_COMMANDS,FPDBG_THREADS,FPDBG_QUEUE,FPDEBUG_THREAD_CHECK,FPDBG_WINDOWS
I am away for some days, so replies may take some time.

Dear all,
I'm not sure whether or not this is an issue with fpdebug, so I'd like to
describe it here first:
I have a main program (Win32 GUI running on Win 8.1) which loads and unloads a
DLL dynamically. I know that fpdebug is currently not able to debug DLLs, but
imho I don't do so, but the issue might be related.
The program runs fine when being run without debugger or when using GDB. However, a crash
occurs when fpdebug is active and the call to "FreeLibrary" is made. The error
is:
Project raised exception class 'External: Unknown exception code
$E0465043'. At address 76EB56E8.
The DLL is my own and I tried to debug the Finalization section with GDB, but I cannot
find an issue there. So imho unloading the DLL should not cause any trouble. As I said,
I'm not trying to actually step into the DLL; I'm only using fpdebug in the main program
and trying to step over the "FreeLibrary" line.
Kind regards,
Thomas
