Hi,
I'm trying to run GNUnet 0.7.0e on a SPARC linux box (Ubuntu.) It
always
crashes after running a few minutes at most. The crash happens always
at
the same spot, which makes little sense to me:
Program received signal SIGBUS, Bus error.

Adding printf's around the htons line made the
crash move forward in
sendBuffer. The difficulty is that I also tested
GNUnet briefly on a
powerpc ubuntu box and there it seemed to run
just fine. I also tried
compiling with gcc-3.4 instead of the default
gcc-4.0. So, I'm quite
clueless. Anyway, are there people running GNUnet
on big endian boxes?
