Hi,
Encountered below segfault during allocation of memory by non - standard
API sdallocx() (jemalloc) all the way from cpp program object instantiate
function().
segfault call stack path is given below. The issue is observed rarely and
not observed often.

}}
in saml_sp_init() function, instantiate() is triggered that in turn travel
through libraries shibsp lib -> xmltooling-> xerces_c() and finally
xerces_c() fail with memory allocation in sdallocx() function which is
NON-standard API of jemalloc().
Request to provide input to debug further on the above crash.
