Description Jonathan Riddell 2014-08-04 16:29:55 UTC

okteta 4.13.97 (4.14. RC) has a compile failure on our ppc64el platform which did not exist in 4.13.90.  (Of course it might be gcc or something else has changed.)  Alas I don't have one of these machines to test on.

Comment 1 Friedrich W. H. Kossebau 2014-08-04 17:06:14 UTC

Nothing in the bytearraymodel_p.* files has changed recently. And there is only one memset call, which other than claimed in the cited warning has not a constant zero length parameter.

Querying my web indexer about the error message indicates that gnu's ld has had some hickups before where it wrongly put out such a problem when there was no reason. So given that builds on other platforms run fine and used to run fine before on this one, I so far think you are hitting a linker/compiler error here.

Seems likely, thanks for investigating
