UTF8bvnormalize bug on 64bit Solaris 8 (ITS#2198)

[miroslav.zubcic@zesoi.fer.hr]

Full_Name: Miroslav Zubcic
Version: 2.1.8
OS: SunOS lav 5.8 Generic_108528-13 sun4u sparc SUNW,Ultra-Enterprise

Submission from: (NULL) (213.202.124.153)


I have compiled OpenLDAP 2.1.8 with gcc 3.2 on Solaris 8. When I try to import
initial
ldif from file with slapadd(8) or re-index base with slapindex, I get SIGSEGV.

If I comment out this line in slapd.conf(5):

index		cn,sn,uid   pres,eq,approx,sub

... then I don't get SIGSEGV. Attributes cn and sn are containing some UTF 8
letters
specific for my language.

OpenLDAP is compiled (entirely) like 64bit application.

Here is basic debug output from some debugger I have found on Solaris 8:
(gdb does not know how to handle 64bit coredumps).

IMHO big is in function which I put in subject ...

I hope I have enough debug information this time. :-)
