[mpich-discuss] gdb + hydra

I'm having some issues doing the following:

mpiexec -n 1 xterm -e gdb -ex r --args ./app ...


this used to work fine for me with 1.2.1 and mpd but seems to give me :

[cli_0]: write_line error; fd=6 buf=:cmd=init pmi_version=1 pmi_subversion=1
:
system msg for write_line failure : Bad file descriptor
[cli_0]: Unable to write to PMI_fd
[cli_0]: write_line error; fd=6 buf=:cmd=get_appnum

also tried :
setenv HYDRA_LAUNCHER_AUTOFORK 0

however it falls over in MPI_Init.
seems like other people experienced this too, but i couldn't find a hint 
that seems to address this issue

i've tried tried 1.4.1p1 and 1.5rc1.

any help would be appreciated.

Kind Regards,
Christoph
