Hi, I am currently using Root 3.05.05 on linux redhat 7.3, located at Cern under /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/ I launch root and execute a simple macros(see attachment) which basicaly open few files, get some tree and draw few histograms: >.x ana_NRJ_sw.C and then I get: > *** Break *** segmentation violation > Generating stack trace... >/usr/bin/c++filt: unknown demangling style `gnu-v3' when I launch root with gdb and then backtrace it, I get: Program received signal SIGSEGV, Segmentation fault. 0x40608314 in G__ST_p0_pointer () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so (gdb) bt #0 0x40608314 in G__ST_p0_pointer () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #1 0x40603396 in G__exec_asm () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #2 0x405f65bb in G__exec_loop () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #3 0x405f6a29 in G__exec_for () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #4 0x405f8f34 in G__exec_statement () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #5 0x40587dca in G__exec_tempfile_core () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #6 0x4058803f in G__exec_tempfile () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #7 0x40601629 in G__process_cmd () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCint.so #8 0x4015832e in TCint::ProcessLine(char const*, TInterpreter::EErrorCode*) () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #9 0x40158431 in TCint::ProcessLineSynch(char const*, TInterpreter::EErrorCode*) () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #10 0x400da044 in TApplication::ProcessFile(char const*, int*) () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #11 0x400d97de in TApplication::ProcessLine(char const*, bool, int*) () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #12 0x40d8af4e in TRint::HandleTermInput() () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libRint.so #13 0x40d89d35 in TTermInputHandler::Notify() () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libRint.so #14 0x40d8b772 in TTermInputHandler::ReadNotify() () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libRint.so #15 0x401adc2d in TUnixSystem::CheckDescriptors() () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #16 0x401ad30a in TUnixSystem::DispatchOneEvent(bool) () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #17 0x40128a2f in TSystem::InnerLoop() () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #18 0x401289bd in TSystem::Run() () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #19 0x400da24e in TApplication::Run(bool) () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libCore.so #20 0x40d8aadb in TRint::Run(bool) () from /afs/cern.ch/sw/root/v3.05.05/rh73_gcc32/root/lib/libRint.so #21 0x08048890 in main () #22 0x42017589 in __libc_start_main () from /lib/i686/libc.so.6 Does anybody know the meaning of this error message: '/usr/bin/c++filt: unknown demangling style `gnu-v3'' and how to get rid of it ? Or is it my macro which is not correct and lead to this crash ? Thanks in advance, Damien Prieur.
