Description: Valgrind detects an invalid pointer read causing a crash in test cases ndb_restore and ndb_view: VALGRIND: 'Invalid read of size 4' COUNT: 2 FUNCTION: Ndb::handleReceivedSignal(NdbApiSignal*, FILES: master.err TESTS: ndb_restore ndb_view STACK: at 0x95A1FB: Ndb::handleReceivedSignal(NdbApiSignal*, LinearSectionPtr*) (Ndbif.cpp:745) by 0x958F28: Ndb::executeMessage(void*, NdbApiSignal*, LinearSectionPtr*) (Ndbif.cpp:175) by 0x9BDC07: execute(void*, SignalHeader*, unsigned char, unsigned*, LinearSectionPtr*) (TransporterFacade.cpp:226) by 0x9C84A9: TransporterRegistry::unpack(unsigned*, unsigned, unsigned short, IOState) (Packer.cpp:109) by 0x9C68A7: TransporterRegistry::performReceive() (TransporterRegistry.cpp:955) by 0x9BE3CD: TransporterFacade::threadMainReceive() (TransporterFacade.cpp:514) by 0x9BE2E8: runReceiveResponse_C (TransporterFacade.cpp:486) by 0x9AD63E: ndb_thread_wrapper (NdbThread.c:82) by 0x4C37C63: start_thread (in /lib64/tls/libpthread-0.60.so) by 0x52F3242: clone (in /lib64/tls/libc-2.3.2.so) Address 0x220 is not stack'd, malloc'd or (recently) free'd The problem is not seen on every run, but it is easy to repeat by running the tests in a loop. How to repeat: (for i in `seq 1 100`; do echo XXX $i XXX; ./mysql-test-run.pl --valgrind-all ndb_restore ndb_view; fgrep Ndb::handleReceivedSignal var/log/master.err && exit 1; done) For me, this repeats the problem reliably after a few runs.
