CPU registers
lazarus / 12-Debugger

There is a CPU Registers window in Lazarus, but I've never seen it
working properly: it just displays random numbers which never update.
This happens under either Windows and Linux, so I guess it's not
something with my OS. I'm using Lazarus 2.1.0. Is anyone experiencing
the same problem?

I assume you are using the gdb based debugger?  If so it may be
similar to issue 38534, which was fixed in commit 433bb3d.  Do you
have a simple test to demonstrate the behaviour?

Edit: There is a similar issue (fix not yet incorporated) with marking
changed registers in fpdebug, but at least the register values should
be correct I think.

Which 2.1 revision? (Current "trunk" is 2.3)

Older that the fix that ccrause linked?

Steps to reproduce?

Do the register show some "unavail" or "evaluating" message when you
step?

On Linux with Lazarus 2.0.12 and the gdb based debugger the register
contents follows my expectation, see attached debugging session.

Вернее всего человек не включил нужный формат числа
(шестнадцатеричное?).

Google translate:
Most likely, the person did not include the required number format
(hexadecimal?).
