glibc 2.3.4 on DEC Alpha segfaults

[Andrew A. Gill]

glibc is segfaulting on DEC Alpha for me.

The last version that works is glibc-2.3.4-0.20040603.1.  The
later CVS versions and glibc-2.3.4-[12] fail.  gdb won't let me
do a backtrace (``no stack''), but I've got the following bits
from ltrace (strace is attached):

xfce4-panel (4.2.0-1):

DEBUG: process_event.c:89: process_event(): event: sysret
(SYS_osf_syscall [0])
DEBUG: process_event.c:73: process_event(): event: signal
(SIGSEGV [11])

dillo 0.8.4 (compiled against the new glibc):

DEBUG: process_event.c:89: process_event(): event: sysret
(SYS_osf_syscall [0])
DEBUG: process_event.c:85: process_event(): event: syscall
(SYS_clone [312])
DEBUG: breakpoints.c:103: disable_all_breakpoints(): Disabling
breakpoints for
pid 32336...
DEBUG: process_event.c:89: process_event(): event: sysret
(SYS_-1 [-1])
DEBUG: process_event.c:81: process_event(): event: exit signal
(SIGSEGV [11])

I'm not sure what's causing this--it may just be that my kernel
(2.6.11) isn't configured for NPTL (glibc-2.3.4-[12].alpha uses
NPTL, right?), or something easy.

Or it could be something hard.  I really don't want to compile
glibc on my system.  Help?

Here's what looks like the relevant part of what dillo was doing:
