Thanks for the confirmation. Yeah, the 1.2.7 (master) is
unstable right
now. There have been a lot of changes going in that haven't been fully
tested with our test suite (we're also having to update the test suite).
I wanted to make a debug build of the server to test the incremental
replication crash i've seen yesterday and used the following commands :
export CFLAGS="-g"
export CXXFLAGS="-g"
export USE_64=1
./configure --prefix=/Local/dirsrv --enable-debug --enable-autobind
Are these parameters correct? Is there any other way to generate the debug
info?
However the debug build i've obtained (from the stable 1.2.6.rc7) in this
way crashes during its startup if i activate USN plugin with ldapmodify
just after setup-ds-admin, then stop-start:
dn: cn=USN,cn=plugins,cn=config
changetype: modify
replace: nsslapd-pluginEnabled
nsslapd-pluginEnabled: on
Non-debug build does not crash, by the way... I think it's because of the
assertion being executed only in debug builds?
Here is the stack trace :
