Oh, I’ve been assuming that it was the *length* that matters.  I’m an old-skool kinda guy, so I’ve been keeping it to 80 columns.

After sending the window full-screen, lookee lookee:

2014/11/04 17:40:58 Ending cygwin install
    112 [main] vi 4424 C:\cygwin64\bin\vi.exe: *** fatal error - cmalloc would have returned NULL
/x: line 6:  4424 Hangup                  vi -c q /var/log/setup.log

It happened on the first run, with a 317x85 window and 9999 lines of scrollback buffer.

Actually, you did the test I wanted: you proved that a different mirror gives the same results, which rules out bad packages on one rogue mirror.  The chance of two bad mirrors is exceedingly tiny, so we can assume the packages are fine, unless they’re corrupt on sourceware, which is also unlikely.

So why not run under mintty, then?  Cygwin runs better under mintty in general.
