This is caused by deltaFormat==0, which leads to format==index_into_fieldBits==0xFFFF... Sorry about not mentioning these to you as well as erack, see http://cvs.fedora.redhat.com/viewcvs/devel/icu/ I have a devicetable fixer there, also the "safety" patch might be relevant for you. issue 72791 was the original "I have some patches to icu that might be of interest" issue FWIW @CMC: Great! Thanks a lot for the info and the patches. @ER: this boosts the priority of issue 72791 quite a bit... *** This issue has been marked as a duplicate of 72791 *** Closing duplicate issue. |
