Hello,
from the subject I don't understand exactly: did you get this crash also
with 1.3.4? Is it reproducible?
Looks like there is a buffer overflow. Can you recompile/reinstall with
memory debug on (in 1.5.x, see Makefile.vars)? The watch the logs and
see if you get any error related to buffer overwritten ops.
Cheers,
Daniel
