That's your problem.

That's the third time people tell me that xmlcatalog.exe from
msys-libxml package segfaults.
I never had this happen to me myself though. Are there any special
circumstances that might have triggered this? Spaces in paths? Overly
long paths? FAT32 filesystem? Non-latin characters in directory names?
Does it happen every time you run the command (the script that invokes
xmlcatalog is the post-installation script for docbook-xml, i think).
Can you run it under gdb and get a backtrace when it crashes?

AFAIR, it can be worked around by rebuilding msys-libxml without zlib
support. Never done that myself either.

If you think it's worth a try, i could try to put together msys-libxml
with debug symbols. And/or a msys-libxml without zlib support.
