I am getting double free core from ldap library. We are running this version of the code (2.4.49 with 2 patches).
git clone https://github.com/openldap/openldap.git -b OPENLDAP_REL_ENG_2_4_49 git cherry-pick 32e965c27134d3d83adbf471186330e361150491 git cherry-pick 5452fb154eaabc46992402a4f1bb1081bc367157
Any idea what could be going on? I am putting the stack trace below:
