Sounds odd, info works fine for me.
Can you make clean && make again, just to be sure. Also, which access
method do you use (mmap or FD). Any additional flags you specified in
to configure? If this still fails, i'd like to know what version of
binutils/cc you are using, and which arch you are on.
If you are not passing anything to configure, please send a bzip2'ed
sample to me directly.
