I've grabbed some more gdb output:

I also tried using owpython without owserver (so with ow.init('u')), this
works regardless of whether thread-support is compiled in.

Hi,
Apparently my new (not yet installed) owserver was still linking to the
libow in /lib, not the freshly compiled one, so now at least I got the
--disable-mt version working. With multithreading enabled the problem
remains however.
owfs is defined as port 10123 in /etc/services.

Wim

Wim,
I ran into a similar problem a little while ago, fixed by making sure that libow
and libfuse were compiled and updated.
By the way, is "owfs" defined as a port?

Subject: [Owfs-developers] owserver segfaulting on startup
Hello,
Has anyone seen the following problem? When starting owserver:
root# ./owserver -u --foreground -p localhost:owfs
Segmentation fault
GDB traceback is included at the bottom. This is on a Fedora Core 5
machine with kernel 2.6.16. Yesterday, with kernel 2.6.15, owserver ran
normally. Since the segfault is in libpthread I tried recompiling owfs
with --disable-mt, but this did not change the result. I'm using the CVS
version of owfs from today (2006-04-07).
Regards,
Wim.
