This is an inquiry about a different problem that's proving elusive to locate. The GNU emacs code is version 18.54 on an HP 9000/370 running HP-UX 6.5 with a patched C compiler. When X11R4 arrived I deleted src/x11term.o and src/x11fns.o, and remade emacs with R4 includes and libraries. No emacs source code has changed, and the only these two object modules have changed. I've done the remake twice, once using +O2 (-O) for the compilations, and once using +O1. Changing fro +O2 to +O1 did NOT change emacs' behavior. The problem happens intermittently when starting emacs. Perhaps 2/3 of the time it starts normally. Sometimes it appears to either hang or loop after its window is mapped but before anything is drawn into the window. When it does this, it usually sits there benignly. On occasion it appears to go wild in some way that floods the system with page-swapping activity. On rare occasions this will virtually disable the system. On one of those rare occasions I tried an extreme abort by hitting control-shift-reset to abort X. To my amazement it didn't abort X, but it DID cure the problem -- the emacs window suddenly came to life; it initialized, loaded the file to be edited, and operated normally. This problem is intermittent. It seems possible that cursor motion or window manager functions might be involved, but I haven't been able to prove that yet. If anyone else has experienced this problem, or has a clue to its cause, I'd appreciate hearing about it. An email message would be best -- I'll be out of town for ~1.5 weeks. ---------------- Paul Raveling Raveling@isi.edu
