Hello,
    I use Insight-20000404 with remote target which
is not very fast and have the following problem:
    When I press 'step" command twice, while the next
pressing seems to be done before the first one was executed this causes
Insight to hang.
    Does somebody more experience such a problem?

We need to know what is the target triplet.

Thanks.

Ugh! Sorry, late Friday, you know...

I am not sure I understand your environment. 
On the message you sent to the list you  posted the output of a native
HPUP 10.10 (hppa1.1-hp-hpux10.20) gdb.  Here you are talking about
BDM which is something that resides on a Motorola PPC
board.
    For some mysterious reason you and Laurent Duperval
connect my message to another one with HPUP!?! I have never seen this computer
in my life, so.....
I am led to conclude that you run on a HPUX 10.20
box but you connect it to a board  using the "target ocd" command,
isn't it right?  Or, due to the "rptoxy" server you use "target
remote" instead?
Note that this is a very unusual behavior and that most probably the
problem is in the part of the code that gets
requests from gdb and handles responses from the target.  If they
are not coded correctly, they lose sync at some
point.  In this case, the rptoxy server is a good candidate as
I never heard any complains of a similar problem with the
standard gdb setup.
    Thanks a lot, we shall search the problem there.
P.S.: I can only answer messages that you post on
the list and the reply must be public as well. I hope you understand.
    Thousands of excuses. netscape's reply command addresses
the first name and doesn't  insert CC. My fault.

Thank you. I'm working on my conversational skills. :-)

Depends. If you live under equatorial skies, chances are it's cold. If you
live under arctic skies, chances are it's warm. Make up your own mind: -3C
when I woke up, slated for a max of 10C sometime today. Sunny, though.

Ugh, early Monday. I thought I was replying to this message I sent last
week:

I get these messages when I run with -nw but in the GUI, nothing seems to
happen:


warning: Unable to find __d_pid symbol in object file. 
warning: Suggest linking with /opt/langtools/lib/end.o. 
warning: GDB will be unable to track shl_load/shl_unload calls

then

Program received signal SIGSEGV, Segmentation fault.
Segmentation fault (core dumped)

GNU gdb 20000204

I'll have to try to upgrade to see what happens.
