Hi Ville,
I started again my previous test running mipl in gdb. Because mip6d is
forking itself (is it the right word?), I typed the following command in gdb
: set follow-fork-mode child.
Then I typed : run -C /usr/local/local/etc/mn.conf -d 5.
You can see the backtrace in the attached file.
Iwill run the same test with the previous version of MIPL.
Thanks for your help
Mathieu
