--- Comment #143 from Luke Kenneth Casson Leighton lkcl@lkcl.net 2013-07-30 19:47:18 CDT --- andrey: that means that there's a case which hasn't been tested for, yet. tracking it down is gonna be fuuun.
could i ask you please to do a "vanilla" (unpatched) install log and to then go through the two log files, doing a side-by-side compare to find the most likely discrepancy that could have caused the failure on the patched version?
it should be pretty obvious: this is pretty fundamental stuff: NamedPipes is at an absolute critical low-level in wine and w32 so it should be blindingly obvious which call is failing, it's just finding the right one and that means doing a side-by-side compare.
