I worked around this problem by doing:
_stp_printf("%4b", *w);
for outputting 4 byte data. You could probably do something similar for
1 byte data.

Is there a way in SystemTap to output binary data with byte
granularity? The only thing I've found is _stp_print_binary() in
embedded C. That outputs in 64-bit chunks. What I'd like to do is
output a buffer of raw binary data that may not be on a 64-bit
boundary. In this case, it's to generate wireshark-compatible packet
data from cifs.
Thanks,
