I have come across an error I dont understand in running some root code.  
I have tried to include the 


command in my code.  I compile without errors but when I run the code I 
get the following error:

*** Break *** segmentation violation
 Generating stack trace...
 0x4068b65e in G__scratch_globals_upto + 0x27 from 
 0x40176439 in TCint::ResetGlobals() + 0x21 from 
 0x4013a698 in TROOT::Reset(char const*) + 0x32 from 
 0x08049067 in main + 0x2f from matread
 0x42015574 in __libc_start_main + 0xe4 from /lib/tls/libc.so.6
 0x08048f9d in TFile::TFile[in-charge](char const*, char const*, char 
const*, int) + 0x31 from matread
Abort (core dumped)

A simplified version of the code is:

#include <cstdio>
#include <iostream>
#include <string>
#include "TFile.h"
#include "TTree.h"
#include "TH2.h"
#include "TCanvas.h"
#include "TVector.h"
#include "TROOT.h"
#include "TCint.h"

using namespace std;

TROOT rootBase("analysis","ROOT analysis environment");
int main()
TFile *file = new TFile ("test.root", "RECREATE");
TTree *tree = new TTree ("tree", "Testing");


And this is compiled with a makefile:

# Makefile
ROOTLIBS        =       $(shell root-config --libs) -lMinuit #-lTable 
ROOTGLIBS       =       $(shell root-config --glibs)
ROOTINCLUDE     ?=      $(shell root-config --incdir)
MATLABDIR       =       /data4/dgrant/Matlab_Inst/extern/lib/glnx86
MATLABD2        =       /data4/dgrant/Matlab_Inst/bin/glnx86

CXX             =       g++
CXXFLAGS        =       -O2 -Wall   -fPIC -I$(ROOTINCLUDE) 

OBJS            =       matread.o

matread: $(OBJS)
-lmx -l
mmfile -lmwservices -L$(MATLABD2) -lmatlb -lmex -lmwmpath -lmwudd -o $@ $^

matread.d: matread.cxx
        @echo "Generating dependency file $@"
        @set -e; rm -f $@
        @$(CXX) -M $(CXXFLAGS) $< > $@.tmp
        @sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.tmp > $@
        @rm -f $@.tmp

include matread.d

matread.o:      matread.cxx matread.h
        $(CXX) -c $(CXXFLAGS) $<

        rm -f *.o
        rm -f *.d

Has anyone come across this before and maybe offer some advice?

Thanks so much!
