Hi,
on -current LyX crashes at startup with "Abort trap" and writes
"backwards memcpy" into /var/log/messages.
Exchanging memcpy in src/support/gzstream.cpp helps. (Tested with
manually applying the patches from ports to downloaded source on 7.5 and
newly sysupgraded snapshot.) I successfully started LyX, created a
document, compiled, viewed and saved it.
My patch to gzstream.cpp below.
Best regards
Robert
