Re: new Cygwin has memory problems? / cygwin1-20041117.dll
cygwin1-20041117.dll, which I got from www.cygwin/snapshots/, solves a few problems, stopping hanging in dired, ispell, and updatedb. (The crash I experienced is getting more common in XP SP2, BAD_POOL_HEADER (www.tweaksforgeek.com/BAD_POOL_HEADER.html)).

I wasn't looking for general the snapshot works feedback. I want to know if the reported problem is solved.
Re: new cygwin has memory problems?
These days I'm mostly visiting the hospital. However, it's unclear just what snapshot to download? I tried cygwin.dll.bz2 and my machine crashed. I'll try to check back here again later. Lester

Re: GLX acceleration / Re: new cygwin has memory problems?
I just saw Christopher's posting re my posting of 12 Nov, explaining that indeed this is a Cygwin-specific problem. Lester +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+= Alexander: I believe the problem to be with the new xorg files, but there are quite a few and I don't have time to reinstall them all. I assume I'll just wait until the next update, but I hope the maintainers will at least keep this potential problem in mind. I have this CPU problem under xterm or rxvt, not only with dired, but also with ispell under mutt in these windows. I do not have these problems at all (using dired or ispell under mutt) under the standard Cygwin console window (no xorg depdendence). I note that dired using ncurses, ans perhaos ispell under mutt might too? Could there be some kind of new conflict with xorg utiltiies? I have all my Curr Cygwin files from mirrors.rcn.net up to date (omitting only setup -- which always seems to revert to Skip when downloaded -- and gcc-testsuite). Thanks for the info on glxgears.

new Cygwin has memory problems?
I was wrong in assuming this was a cygwin base problem. It must be a cygwin-xfree problem. I have no problems I can see in a cygwin console window, only in an xterm (or rxvt) window running under XWin -unixkill -emulate3buttons -clipboard -multiwindow -silent-dup-error Lester +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+= I cannot determine why, but with the new Cygwin base I just installed, a utility I have used for quite a few years, dired [http://www.math.utah.edu/~beebe/software/file-tools.html#dired], now freezes my window.

Re: new Cygwin has memory problems?
After seeing the posting by Christopher Faylor (posted after mine), I checked mirrors.rcn.net (my usual default), and it seems I already am up to date, and my problem still persists. +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+= I was wrong in assuming this was a cygwin base problem.
