hello,

It would be really helpful to attach the output of nmv_log_domains="gdbmi-output-domain nmv-gdb-engine.cc" nemiver > out.log so that we have more information.

My feeling is that the gdbmi parser is being fed with a partial gdbmi input.
So the nemiver/gdb communication controler may be cutting some messages it receives from gdb. I am not sure about that though. More logs should greatly help here.

Thank in advance,

Dodji.

hmmh, Okay. Trying to reproduce that bug myself, I got a smiliar output that I have pasted below. I will try and work on this.

It seems gdb is returning a truncacted content. That behaviour can be reproduced with a bare gdb:

gdb --interpreter=mi2 .libs/example

b main
run
-data-evaluate-expression window

You can see that the content of the variable "window" returned by gdb is truncated. So I must make the parser understand that broken output, and try to debug that at the gdb level one day. /me sighs.

.... oh my ...
that sucks. Does it behave the same with the non-mi interface?

The non mi interface does not send the information the same hierarchical format, and thus does not exhibit the same flaw.

I have pushed changeset r723 to svn trunk. That changeset should hopefully fix the problem.
