Re: Crash running Cygwin bash shell under XEmacs

Hello Henry, hello All! I debugged this a bit in XEmacs 21.5-b32 "habanero" febc025c4e0c+ tip configured for `i586-pc-win32'. See attached INSTALLATION file. I am tesing this with CYGWIN_NT-5.1 Kuckuck 1.7.16(0.262/5/3) 2012-07-20 22:55 i686 Cygwin installed. I am running with CYGWIN=detect_bloda pipe_byte nodosfilewarning Have uninstalled Google Desktop Search when I got this: Potential BLODA detected! Thread function called outside of Cygwin DLL: C:\PROGRA~1\Google\GOOGLE~2\GOEC62~1.DLL After making sure no cygwin processes are running I also ran Start->Run->ash /usr/bin/reabaseall -v which looked good. Finally, I ran xemacs under Visual C++ 2008 Express Edition and provoked the scenarios where * bash run as M-x shell would die upon startup 5 [sig] bash 7436 exception::handle: Exception: STATUS_ACCESS_VIOLATION 6589 [sig] bash 7436 open_stackdumpfile: Dumping stack trace to bash.exe.stackdump Process bash exited abnormally with code 35584 * M-x epa-list-keys would come up empty because gpg dies as well Here's the relevant bit of source code from src/process-nt.c with line numbers 1045 if (!windowed) 1046 enable_child_signals (pi.hProcess); 1047 1048 ResumeThread (pi.hThread); In both cases I found the cygwin process under construction (bash or gpg) to die when https://bitbucket.org/xemacs/xemacs/src/b0d40183ac79/src/process-nt.c#cl-... is executed. Skipping over https://bitbucket.org/xemacs/xemacs/src/b0d40183ac79/src/process-nt.c#cl-... will allow them to live and they appear to function normally. M-x epa-list-keys produces the expected list of key in the buffer M-x shell can be interacted with for simple commands like pwd, which which, ls, but obviously lacks interaction with signals and ssh to another host will not work: bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell AichnerAd＠Kuckuck:/cygdrive/c/Hacking/v8.googlecode.com/v8/build$ ssh adrian(a)apa.p8x.de Pseudo-terminal will not be allocated because stdin is not a terminal.

I can contribute some debugging bits if there's interest but will not do any further investigations for now. Oh, BTW, I also installed the latest cygwin emacs package: (emacs-version) "GNU Emacs 24.1.1 (i686-pc-cygwin, GTK+ Version 2.24.10) of 2012-07-18 on fiona" and both test cases (M-x epa-list-keys, M-x shell with working ssh to other system from there) work fine there, but that's obviously a cygwin build, unlike my native Windows XEmacs build.
