Apache 2.2 coredumping on Solaris with Subversion 1.6

Hi,

 

I compiled subversion with apache 2.2 on solaris but when I hit the server with any request, it produces a core dump. Running a pstack on the core file produces:

 

# /bin/pstack /bb/cores/core.httpd.5718.1257279721

core '/bb/cores/core.httpd.5718.1257279721' of 5718:    /bb/web/apache_2_2/bin/httpd -k start

Ive seen several other posts with people having the same issue but no real solutions

etc.. Ive recompiled the mod_dav_svn.so with the –g CFLAGS but don’t see any real debug o/p in the core file.

Any help is appreciated.

Running the core files through dbx gives me :

 

Reading libz.so.1.2.3

Reading libm.so.1

Reading libgcc_s.so.1

Reading mod_jk.so

t@1 (l@1) program terminated by signal SEGV (Segmentation Fault)

Current function is access_checker

  548     authz_svn_config_rec *conf = ap_get_module_config(r->per_dir_config,

 

Has anyone faced anything similar or have any ideas about how to fix this issue?
