Re: reproducible memory problem and crashes on cygwin: TRACEBACK INCLUDED
here is a traceback of a crash under cygwin. am happy to provide more information, but please note that I am a total ignorant and needs very specific instructions on what to do in gdb etc. thanks for any feedback...

Re: reproducible memory problem and crashes on cygwin
From: Nick Roberts [EMAIL PROTECTED] thanks so I get nil in the echo area and the memory usage does not change at all when I try this. I didnt try leaving emacs for 1/2 an hour. it normally crashes with a segmentation something much earlier. Spontaneously? If you post a backtrace as Eli suggested (as described with M-x report-emacs-bug), someone might be able to understand the problem. I did that a few times last year but no one was able to help. I could try again. but this memory thing seems to be easily reproducible. Am I the only person in the universe running cvs emacs on cygwin? no emacs cygwin maintainer currently around? _ Express yourself instantly with MSN Messenger!

Re: reproducible memory problem and crashes on cygwin
From: emacs user [EMAIL PROTECTED] Bcc: Date: Mon, 10 Jul 2006 01:05:40 -0400 Thank you for your report. this problem leads to consistent and reproducible crashes of emacs. You didn't show any crashes. Please do (with meaningful backtraces). using latest cvs gnu emacs (22.0.50) on latest cygwin. Which version of Cygwin is that? We had in the past reports about various problems in specific versions; please try to search the archives of this list and of emacs-devel, and see if your crashes resemble some reported in the past. start with emacs -q --no-site-file edit a jpeg file kill buffer edit another jpeg file kill buffer again. every such jpeg file edited and exited leaves the memory used by emacs (as seen in the list of processes of the windows task manager) increased. Please report the numbers: the memory usage figures reported by the Task Manager before, during, and after the image buffer is killed. Memory does not decrease once buffer with image is killed. when a text file is edited and exited, the memory does return to its original size. I don't think Emacs returns the memory to the OS immediately, but GC should cause that. ___ emacs-pretest-bug mailing list emacs-pretest-bug@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug
Re: reproducible memory problem and crashes on cygwin
From: Eli Zaretskii [EMAIL PROTECTED] From: emacs user [EMAIL PROTECTED] Thank you for your report. this problem leads to consistent and reproducible crashes of emacs. You didn't show any crashes. Please do (with meaningful backtraces). so emacs uses more and more memory, and eventually slows down my laptop so much that I either have to kill it (OK, not exactly a crash, I suppose), or that it somehow dies. wouldnt this be sufficient information to the cygwin maintainer to work with? even without the crash, this seems like a fairly significant bug...? using latest cvs gnu emacs (22.0.50) on latest cygwin. Which version of Cygwin is that? We had in the past reports about various problems in specific versions; please try to search the archives of this list and of emacs-devel, and see if your crashes resemble some reported in the past. the cygwin home page suggests that Latest Cygwin DLL release version is 1.5.20-1 is this what you were looking for? how do I find the cygwin version number? I am trying to be well intentioned but am certainly a total ignorant as a non fortran programmer I did follow the links you suggested in a previous email, but couldnt understand if they are relevant or not to this specific problem, or the previous one I reported. start with emacs -q --no-site-file edit a jpeg file kill buffer edit another jpeg file kill buffer again. every such jpeg file edited and exited leaves the memory used by emacs (as seen in the list of processes of the windows task manager) increased. Please report the numbers: the memory usage figures reported by the Task Manager before, during, and after the image buffer is killed. an example: before editing the image: 33Mb during: 39Mb after killing the buffer: 39Mb image file is 186263 bytes large (jpeg) Memory does not decrease once buffer with image is killed. when a text file is edited and exited, the memory does return to its original size. I don't think Emacs returns the memory to the OS immediately, but GC should cause that. I'll take your word for that, I hardly know what GC is... _ Dont just search. Find.
