trouble with openldap >2.4.16


I am having trouble with Segfaults on Solaris Sparc, it seems like the sporadic error that some people have coming up during testing, but not others.

Oddly, this only happens for me on an older not-patched box myunhappyserver, and NOT a more recently patched box myhappyserver (same slapd/bdb binaries and libraries)

The "new" box (happily runs all openldap versions i have tried, up to and including the stable version based on 2.4.19) is :

SunOS myhappyserver 5.10 Generic_141414-07 sun4v sparc SUNW,Sun-Fire-T200

The "old" box (segfaults even on simple start sometimes - but very occasionally it will run for awhile before it segfaults) is :

SunOS myunhappyserver 5.10 Generic_127111-11 sun4v sparc SUNW,Sun-Fire-T200

From adb on "myunhappyserver" i get (in response to "adb slapd core_qgpro01_slapd_404_404_1260924086_4710") :

If i can do any more useful things with adb or the like, please provide some example and i'll run it.

The ldd for slapd on the "new" server returns :

The ldd for slapd on the "old" server adds (which would appear to be harmless) :

       libcmd.so.1 =>   /lib/64/libcmd.so.1

All compiled libraries are 64 bit, linked against the 64 bit solaris libraries.

I am using the same libraries for berkeley 4.8, on all servers.
