Seems like the crashes happens because of abi::__cxa_demangle() for mangled symbol name " _ZNSt9_Any_data9_M_accessIPPZN5folly6fibers12FiberManager16runInMainContextIZN8facebook8memcache15CacheClientImplINS6_17CControllerCommonINS1_7dynamicEEEE11multiOpSyncINS6_11McOperationILi11EEESt6vect ".
This is blocking us from releasing our C++ debugging support. Anyone know of a quick workaround I can fix it locally? Thanks!
