Description Branislav Náter 2012-05-15 14:03:31 UTC 
Description of problem:
Multibyte tests from tcsh upsream suite are failing on i386 architecture.

Version-Release number of selected component (if applicable):
tcsh-6.17-19.el6_2

How reproducible:
always on i386 architecture

Steps to Reproduce:
1. run upsream test suite (/CoreOS/tcsh/Sanity/upstream)
  
Actual results:
121: EUC-JP multibyte test                           FAILED (mb-eucjp.at:90)
122: UTF-8 multibyte test                            FAILED (mb-utf8.at:90)

Expected results:
121: EUC-JP multibyte test                           ok
122: UTF-8 multibyte test                            ok

This seems like like working fix:

  diff --git history-file-locking.patch history-file-locking.patch
  index 7e8b02f..b6db21e 100644
  --- a/tcsh-6.17.00-history-file-locking.patch

  ++    lseek(fildes, -(off_t)partial, SEEK_CUR);
        errno = err;
        return res != 0 ? res : r;
    }

There was probably mistakenly removed (off_t) retype expression in
history-file-locking patch.

Another problem with this patch was found by Coverity (use after free):
