Thank you for filing the bug.  Please append also the output of 'locale'.

here is the 'locale' command output:

Thanks!  I am able to reproduce the crash:

$ export LC_ALL=en_US.ISO-8859-1
$ gdb -q --args tr '[:upper:] ' '[:lower:]'
(gdb) run

Comment 5 Kamil Dudka 2010-07-08 14:13:54 UTC
I see the same bug in the upstream git HEAD.  However it's not easy for me to track it down.  It does not crash with C locales, but it does with en_US.ISO-8859-1.  The key problem is that is_char_class_member() returns different results for chars >127 if the locales is changed.  If I switch to C locales only within this function, it works again.

Comment 6 Pádraig Brady 2010-09-22 11:34:52 UTC
Ah that's well broken.
It stems from the assumption that there are the same number of
upper and lower chars. However for en_US.iso-8859-1 for example
there are 56 and 59 respectively.

This also messes up in the other direction,
and this incorrectly transforms 0x20 to 0xDE:

  echo "_ _" | LC_ALL=en_US ./src/tr '[:lower:] ' '[:upper:]'

I'll fix it soon upstream and post the patch here.
