I've been looking further into this in the meantime and have found the
problem.
I enabled debugging, NODAEMON and NOFORK in the server and started adding
debug statements [I found out it was segfaulting somewhere], and it appeared
to segfault in the following line in setupexport:
msg3(LOG_INFO, "Size of exported file/device is %Lu", (unsigned long
long)client->exportsize);
Just by commenting that one out everything works. I don't really understand
why, perhaps something with the unsigned long long cast and gcc on an ARM
device?
Greets,
Robin.
