[sword-devel] Segmentation fault - was Re: SWORD 1.7.0RC3

[Peter von Kaehne]

I hate to bring this up, now, when we really all want 1.7 out, but
current svn head produces a segmentation fault in imp2gbs. The other
utilities insofar as I tested them seem to be fine.

Below the stacktrace. Tell me if you need more. I basically use
usrinst.sh produced binaries, with the only modification that I changed
the install directory to /usr/local/bin
