[sword-devel] osis2mod segfault

[Manfred Bergmann]

Just ran osis2mod from SWORD version 1.5.11 to create a module which  
ran fine so it can't be the XML source.
And even if the problem would be in the XML source osis2mod shouldn't  
crash with segmentation fault.
It is hard for me to track down this problem and I guess someone with  
more knowledge of the SWORD engine has to help here.
I suspect that somewhere either in osis2mod or in the engine is a  
problem.

I've also compiled versions of 1.6.0 and 1.5.11 on Ubuntu 9.04 and ran  
osis2mod which produced the same result.
1.5.11 worked, 1.6.0 not but here it stopped at book Hosea already  
where with the latest SVN head crashed at Joel.

btw: why are only the old binaries of SWORD 1.5.9 available as package  
on Ubuntu?


Cheers,
Manfred
