gdb a ice server 3.1.0

hey,

ive got a strange problem when i try to gdb my code.
the debuggger stops when i 'next' over InitialisationData initData. when i step into i get over that statement but the server stops when i do another 'next'

because i did not actualy do something with ice yet i think its something in the ice runtime what makes the gdb choke.

i append the debug session for you to see the problem - have you any idea (compile flags, changes in Ice::Application etc) that could cause the problem?
gdb worked with 3.0.1 but did never with 3.1.0. starting the server without debugger works fine too.

thanks for comments

    That's odd. We use gdb all the time :)

    Can you give us some more details about the environment you are seeing this with? Relevant information might be:

    - OS (if Linux please indicate distro and version)
    - Are you using a binary distribution of Ice or did you build it yourself?
    - Compiler version.
    - GDB version.
    - Anything else that you think might be relevant.

    Cheers!

    i found the bindist of ice is somewhat windows optimized (just by the volume of the download area) so i thought you might have missed testing the gcc - how narrowsighted of me :(

    this morning i found the iceservers together with the gdb in my ps stopped - it obviously was friday and too hot.
    to investigate my real problem i started the debugger with 3.0.1 and found a segfault in my code.

    i suppose there was a problem with my mixed libs - when i got time ill upgrade to 3.1.0 again and provide more information.

    peace

    process tree

    i figured out a reason:
    when i gdb the ice-server in a mc (midnight commander) subshell (in a screen in a ssh...) this debugging problem happens - if i dont everything is fine

    whatever system boundary i reached there :rolleyes:

    peace
