TR: HTTP 500 error since HG 1.9/1.9.1 - was fine previously (until HG 1.8.4)

Thu Aug 18 12:27:01 UTC 2011

The Url of P. Mezard (cocorico) is http://mezard.eu/hgbuilds/ I think.

Do you keep compiling on each and every new version of HG?
Do you know if there is an open-ticket for this (I didn't find any but may have use wrong keywords), or any HG developer working on it?

This has been the case for a while now (since 1.8 maybe)
Using a version compiled with mingw avoids it. That's what I use.
Pmezzard usually has a mingw version of stable built, but I keep
forgetting the URL to where he has them shared.
