URGENT: Apache HTTP Migration from 1.3 to 2.4 UNIX Solaris

[singhal.ankit@xxxxxxx]

Dear All,

I have migrated a user module mod_example
from 1.3 to 2.4. But when I try to start the apache it is giving a segmentation
fault and creating a core.
Installed binaries:
Apache 2.4.34
apr-1.6.5
apr-util-1.6.1
pcre-8.40
expat-2.1.0

Following is the stacktrace while debug:
t@1 (l@1) signal SEGV (no mapping at
the fault address) in strlen at 0xfefcceb8
0xfefcceb8: strlen+0x0018:    
 ldub     [%o2], %o1
Current function is apr_pstrdup
   77      
len = strlen(s) + 1;
(dbx) where
current thread: t@1

0xed558, 0x1, 0x0), at 0xfefcceb8

Following is the pstack of core:

-k start
 fefcceb8 strlen   (b8190,

830b8, a9624, e01a8, 0) + 24c
 00081fac main     (b8190,

 000382fc _start   (0, 0,
0, 0, 0, 0) + 5c

This is happening while loading a user
module that I created:
LoadModule example_module modules/mod_example.so

Please provide your valuable insight
into it so that I can go forward.

Thanks & Regards
