[CentOS] Problems in x86_64 Centos 5

We upgraded a 64 bit server from Centos 4 to 5 and encountered some 
strange problems. Tcsh segfaulted irregurarily and emacs gave irregurarily
strange error messages about regular expressions. Both problems 
disappeared when a 32-bit version was installed instead of the 64-bit.
Ldconfig still occasionally segfaults.

64-bit servers where Centos 5 was installed from scratch have no problems.
It is like there were some sort of remnant of the previous OS, but I
can't figure out where.

Strace of a 64-bit tcsh usually ends like this:

open("/usr/lib/locale/locale-archive", O_RDONLY) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=55537056, ...}) = 0
mmap(NULL, 55537056, PROT_READ, MAP_PRIVATE, 3, 0) = 0x2aaaaaae0000
close(3)                                = 0
brk(0)                                  = 0x15b30000
brk(0x15b30800)                         = 0x15b30000
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

and ltrace gives:

__libc_start_main(0x405180, 1, 0x7fff89087298, 0x440b30, 0x440b20 
<unfinished ...>
setlocale(5, "" <unfinished ...>
sbrk(0)                                                   = 0x141f1000
sbrk(2048)                                                = 
0xffffffffffffffff
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

Does anyone have any ideas?
