Error: No memory for static ...

Hello,

I'm trying to write a macro to read in values from a TTree in a root file. The following minimal example fails:

#include "TFile.h"
#include "TTree.h"
#include "TBrowser.h"
#include "TH2.h"
#include "TRandom.h"
#include "TCanvas.h"

void read_tree_minimal()
{

   TFile *f = new TFile("Ca1Mn47d.lowsanidined.20080506.135053.root");    static Double_t energy;
   return;
}

root [0] .x read_tree_minimal.C
Error: No memory for static energy\23b\0 read_tree_minimal.C:12:

The same macro compiles without error:

root [1] .x read_tree_minimal.C++

Info in <ACLiC>: script has already been loaded in interpreted mode
Info in <ACLiC>: unloading /home/rmason/test/root/./read_tree_minimal.C and compiling it
Info in <TUnixSystem::ACLiC>: creating shared library /home/rmason/test/root/./read_tree_minimal_C.so
/home/rmason/test/root/./read_tree_minimal.C: In function 'void read_tree_minimal()':

/home/rmason/test/root/./read_tree_minimal.C:11: warning: unused variable 'f' /home/rmason/test/root/./read_tree_minimal.C:12: warning: unused variable 'energy'

Perhaps someone would be kind enough to point out what is wrong.

Thanks,
Roger
