This code is #if 0'ed out without comment. Right. I think I should have put a comment on that, because now I don't remember exactly why I did it. It probably interferes or causes a crash with malloc debugging enabled. >> I made a test on Demeter last night before she died, and I could not >> reproduce the exit(3) crash described above, but that may be due to >> differences between glibc-2.1 and glibc-2.0.7preX, or something else. >> I have upgraded practically everything between March of 1998 and now. > Note: The crash only occurs on glibc 2.1.1 (<-- Note the patch > level). O.K. Demeter was the only machine with glibc 2.1, so I cannot test this at present. -- I protest the NATO war in Yugoslavia.

pgp key for the package list 25 years, 6 months

Earl Stutes

Here are the final few lines of output when running gpg package-index-1999-05-27.sig gpg: Signature made Thu May 27 02:04:04 1999 PDT using DSA key ID DCF80B6B gpg: requesting key DCF80B6B from wwwkeys.us.pgp.net ... gpg: no valid OpenPGP data found. gpg: Total number processed: 0 gpg: Can't check signature: public key not found This is apparently causing a failure of the package list & install code in my xemacs-21.2 beta14. You might also be interested to know what pgp5 does. pgpv package-index-1999-05-27.sig Opening file "package-index-1999-05-27" type text. unknown hash: unable to verify signature I have really appreciated the Manage packages features and hope you get it repaired soon. Thanks =eas=

Something which must be tested is how this will work with the old GNU malloc in XEmacs. Hand patch src/m/alpha.h to look like: /* #ifdef LINUX */ # define SYSTEM_MALLOC /* #endif */ ;; Urgh! How did XEmacs end up with this indented preprocessor line ;; crap? Rerunning configure should have it build with the old GNU malloc (configure will call it the "New GNU malloc", but you can ignore it). If this works it still doesn't rule out a compiler bug or an XEmacs bug. -- I protest the NATO war in Yugoslavia.

Could you compile with debugging enabled (i.e. -g), so that you can use the debugger where to see where it is hanging?

One symptom on OSF is that the character hash tables are read-only. The easiest way to demonstrate the damage is to start the program up, enter a string of hiragana (or cut & paste out of a file like its-hira.el), select it with the mouse then do `M-x japanese-katakana-region'. Please ignore my previous message regarding changing mallocs. The instructions are wrong. -- I protest the NATO war in Yugoslavia.
