debugging a seg fault

Hi,

I'm testing a program that reads a rootfile and makes histograms from a tree. The program fails with a seg fault at the marked line:

  const Long64_t nenergies = v1.size();
#ifdef DEBUG

  cout << "Nenergies = " << nenergies << " at " << "line " << __LINE__ << endl;
#endif

  Int_t word[nenergies][48]; // <---------- SEG FAULT
#ifdef DEBUG

  cout << "Line = " << __LINE__ << endl;
#endif

The value of nenergies at that point is 104554, much smaller than the maximum size of a Long64_t.

I'd apperciate suggestions on how to debug this further.

Thanks,
Roger
