GDB traces and olcConfig
Dear all,
I am trying to configure back_meta for testing virtual directory.
Attached is my config. It may not make sense.
Trying to change configuration under
olcMetaSub={0}uri,olcDatabase={1}meta,cn=config
From :
{5}rewriteRule "^(.+uid=[^,]+)(a)domain.two.com(,.*)$"
"${&&target(\"ou=people,dc=domain,dc=two,dc=com\")}$1$2"
":"
To:
{5}rewriteRule "^(.+uid=[^,]+)(a)domain.two.com(,.*)$"
"${&&target(\"ou=mynetworkpeople,o=my.example.com\")}$1$2"
":"
I get a segfault.
Please find attached the gdb traces.
Before segfault, slapd is able to log the following messages:

I see, the LDIF you attached is not the same as what you pasted in your earlier
reply. I've now reproduced and fixed the issue.

Hi Howard,
I will require a few day before I am able to come back to you with valgrind
traces.
I just retried to post gdb traces in case they contain more useful
informations.

Thanks. Still not able to reproduce, even with multiple repetitions of this
modification. Can you run under valgrind and still reproduce it?

New gdb traces
Hi Howard,
I retried to reproduce the issue and was thinking it always occured, but
indeed I had to insist to finally trigger a SIGABRT.
I hope the gdb traces attached will help you to identify the issue.
Best regards
Manuel FLURY
Can you confirm that the modify request you used is identical to the one I
tested?

Unable to reproduce.
Using this modify LDIF, ldapmodify works fine.
