Doc Text:	A defect in the character conversion routines for the IBM930, IBM933, IBM935, IBM937, and IBM939 character sets could result in a redundant shift sequence being output under certain library internal conditions. The redundant shift sequence makes the output non-conforming and can result in an inability to read back the output data. The character conversion routines have been corrected and no longer output a redundant shift sequence.	Story Points:	---

Description Jacob Hunt 2015-11-10 20:56:51 UTC

Created attachment 1092445 [details]
input file for iconv

Description of problem:

When a shift character is emitted at the end of the buffer the internal
shift state is not updated, causing the next round to emit another shift
character.

Version-Release number of selected component (if applicable):

glibc-2.12-1.166.el6_7.1.i686
glibc-2.12-1.166.el6_7.1.x86_64
glibc-common-2.12-1.166.el6_7.1.x86_64
glibc-devel-2.12-1.166.el6_7.1.i686
glibc-devel-2.12-1.166.el6_7.1.x86_64
glibc-headers-2.12-1.166.el6_7.1.x86_64

How reproducible:

always

Steps to Reproduce:
1. Use the attached file to run through “iconv -f utf8 -t Cp935”

Actual results:

The resulting file has two "SI" outputs together where just one should be present.

The upstream bug (https://sourceware.org/bugzilla/show_bug.cgi?id=17204) is still open and none of the patches has been committed.

That should be upstream bug 17197.

To be fully accurate, we are unable to include it in a future release of Red Hat Enterprise Linux 5, though we do hope to fix this in later major releases of Red Hat Enterprise Linux.
