Thanks for the bug report.
Unfortunately tla mainline 1.3.1 is known to have a few segfaults (some
of which I fixed as I found them).
Where did you get 1.3.1? Just trying to figure out which exact version
you are using. Unfortunately with the cygwin port, there have been many
different attempts. I will start with assuming that you got my version,
but it is probably more likely that you got Lode's.

After installing tla-1.3.1/cygwin I want to rebuild the history of my
project. For this I am trying to tla get from a remote mirror on a
debian host.
This appears to go well up to revision ...-patch-17 but I get a segmentation
fault when patching for the next revision, which contains a lot of
metadata changes to files and directories.

Most likely there is some meta-data that I failed to catch, and
hide/rename properly.

Honestly, though, I have stopped working on tla-1.3.1 for cygwin. I'm
the only one who seemed to actively use it, and I switched to working on
a version of baz instead. Specifically, you can go to:
I try and keep it up-to-date with the latest development version of baz
(I probably check about 1/week).
If you look at the attachments for that page, you can get older
versions, though generally the latest one is the best to get.

And I have a version of baz using the dos8.3 trick (it accesses files
using their short DOS8.3 name, rather than using =dirnames). The bundle
needs to be extracted and put into /usr/local/bin.

Unfortunately the dos8.3 versions are not compatible with my older
short-path versions or the dirname versions. (The baz-dos version *is*
compatible with the tla-dos versions)

To switch, you need to delete your working directories and revision
library, and start over. Yes, I know it is a pain, I went through the
same pain myself. But it is more stable, and more likely to be
maintained, because it is overall a less invasive change.

This is with a recent version of cygwin is version 1.5.18-1

The failing patch-18 has a lot of meta data changes to many files and
directories, including the {arch} directory .. could this be the source
of the crash?

Possibly I am doing this all wrong ... what is the recommended way to
migrate from tla-1.2.1-dirnames to tla-1.3.1 on cygwin?

It depends which version of 1.3.1 you are using. If it is Lode's latest
work, he got rid of =dirnames support, in favor of the dos version. I
ended up going the same route (favoring dos instead of short-path or

Switching from dirnames or shortpath to dos means that you have to
delete your old directories and revision library, and re-create them
(make sure you commit all of your changes first).

We probably could meet on IRC if you need more help than that.
