[PVFS2-developers] current cvs weirdness

Is anyone besides me seeing anything strange with the current cvs 
snapshot?  This fails for me on a single server/client setup:

./pvfs2-cp /etc/hosts /mnt/pvfs2/foo

The error msg printing is broken in the case that I am hitting, so the 
output isn't very helpful.  However, looking in gdb I see that bmi has 
been asked to send 16 buffers in a list operation generated by a flow, 
and the writev call gets a EINVAL.  I'm pretty sure that copying this 
small file should only require one buffer.

Oddly enough, everything looks fine when I run pvfs2-cp through 
valgrind, and I get no error.  So.. maybe this is some subtle timing or 
memory thing that doesn't show up all the time.  It hits me every time 
right now though :)

I don't know where this problem came from yet.  Just randomly backing up 
a bit it looks like cvs from 6 weeks ago is fine, but maybe cvs from 3 
weeks ago is not?

I'll continue digging (or maybe just narrow down the working cvs 
versions until I find the suspect commit), but I just thought I would 
hit the list in case anyone has ideas...
