[Koha-zebra] zebraidx: corrupted double-linked list, when ICU enabled

[Frédéric Demians]

Hello,

When indexing a Koha set of biblio records containing Arabic characters, 
zebraidx crashes with this error message:

*** glibc detected *** zebraidx: corrupted double-linked list: 
0x00000000017feb20 ***

If the same set of records are indexed by zebraidx one by one, it works.

If ICU is disabled is also works.

So this bug seems to be Zebra + ICU related.

I suspect there are 'invalid' Arabic characters somewhere but I can't 
see anything special.

Does it sound familiar to anybody? Does anyone find a solution for this bug?

Thanks.
