I never have any problem during other actions with the remote VDR (recording, viewing, place cutting marks,...) _exept_ when i start the cutting procedere itself with the keyboard shortcut "2". Most times (> 95%) the remote vdr segfaults immidiatly. The file structure is still created (%foobar ff.). In the few times when it not segfaults then the cutting is done well without problems.
Hello again,
I've learned that i could also start the cutting process on the vdr server itself, without a frontend. With this i also (and 100% reproducable) got the segfault of the vdr.
I start without a running vdr: s01# vdr -u vdr --edit=/video/Die_Marx_Brothers_im_Kaufhaus/2012-10-29.01.48.50.99.rec/ and also with a still running vdr and call the --edit with another instance: vdr -u vdr -i 1 --edit=/video/Die_Marx_Brothers_im_Kaufhaus/2012-10-29.01.48.50.99.rec/
From both tries i make backtraces with gdb, both differs only in thread numbering etc. So i attach the one with -i 1 instance, along with the vdr logfile output. Maybe one of you see a clearer picture why this segfaults happen here.
I attach logfile sequence and backtrace output together.
Regards and TIA

Ok I looked at cutter.c again and now I think I found the cause: Linux must default to bigger thread stacks than FreeBSD, FreeBSD's default seems to be 2 MB on amd64 and MAXFRAMESIZE is almost 1 MB... Try the patch below, you can put it in files/patch-z-cutter.c in the port dir. (the thread.c part is FreeBSD port specific, it caused a different crash with --edit.)
