When checking out one of the subsystems from our repository, the
check-out always fails for one of my colleagues with the following
error messages after about 2/3 of the files:
svn: E155009: Failed to run the WC DB work queue associated with
'$HOME/C8-32-C-serf/CCS/db/src', work item 9694 (file-install
CCS/db/src/dbBackupSingleAttr.c 1 0 1 1)
svn: E000012: Can't create a character converter from 'UTF-8' to native encoding
The same check-out works for me without any problems using the same
svn client on the same machine.
The difference is in the setting of the LANG environment variable.
When set to "en_US.UTF-8", everything works as it should, but with
LANG=C, the check-out always fails.
The svn client is version 1.8.0 (from the CollabNet rpms), 32-bit(!),
running on a 64-bit Linux installation.
I ran several experiments with both 32-bit and 64-bit installs of
1.7.10 and 1.8.0, all on the same and all checking out to a local
disk, with both language settings. The results are below.
Summary: the 64-bit clients worked in both versions, only the 32-bit
1.8.0 client fails. The 1.7.10 client failed with a different error
when I tried to use serf for better comparison to the 1.8.0 client,
but worked fine with the default neon library.
We would like to switch to 1.8.x but are unfortunately forced to run
32-bit clients because we need to interface with a 32-bit Exclipse
installation for vxWorks.
But I don't see why 64-bit client should be required in the first
place. A simple thing like a check-out should not consume large
amounts of memory. I suspect that there is some kind of memory leak
here. The results below show that 1.8.0 requires much more memory than
1.7.10 with neon (see the numbers for "maxresident").

The language settings used in the commands below:
l1=en_US.UTF-8
l2=C
The check-out is always from the same URL to a fresh working copy. The
name of the wc is on the line below the command. The following lines
are the output of the "time" command or the error message from svn.
