xemacs 21 doesn't build on Alpha Linux

Hi, I'm attempting to build xemacs 21 for Alpha Linux. Unfortunately, both 21.4.12 and 21.5 (CVS) fail: [...] ./xemacs -nd -batch -l /src/xemacs-21.4.12/src/../lisp/update-elc.el Error before initialization is complete! Fatal error: assertion failed, file eval.c, line 1880, abort() make[1]: *** [update-elc.stamp] Aborted (core dumped) make[1]: Leaving directory `/src/xemacs-21.4.12/src' make: *** [src] Error 2 [...] ./xemacs -nd -no-packages -batch -l /src/xemacs-21.5/src/../lisp/update-elc.el Fatal error: assertion failed, file alloc.c, line 326, !in_malloc make[1]: *** [NEEDTODUMP] Aborted (core dumped) make[1]: Leaving directory `/src/xemacs-21.5/src' make: *** [src] Error 2 This is on an Alpha EV68 running Debian GNU/Linux, gcc version 3.2.3 20030221 (Debian prerelease), binutils 2.13.90.0.18. Any ideas? -- Falk
