The command below results in "internal compiler error: Segmentation fault" with the checking-
enabled version of GCC 4.0.1 on Suse Linux 9.2.  It also crashes with Apple GCC 4.0.0 on Mac OSX 
10.4.2.  
    GCC 3.3.4 on Suse rejects the code without crashing, as does CodeSourcery arm-none-linux-
gnueabi-g++ 3.4.3, our local version of arm-softfloat-linux-gnu 3.4.1, and (on OSX) Apple's GCC 3.3 
and my own build of 3.4.0.

/opt/gcc401chk/bin/g++     -c       ../cpp/bugfiles/error/EckelRob_104822.ii 

../jammed/Barney/eckel.cpp: In function ‘std::string EckelCode::FramisTest()’:
../jammed/Barney/eckel.cpp:2039: internal compiler error: Segmentation fault

    With the Apple version of GCC 4.0.0, it gives a crash dialog (with a Report… button which doesn't 
work) with the following text:

The application cc1plus quit unexpectedly…
EXC_BAD_ACCESS (0x1)
KERN_PROTECTION_FAILURE (0X2) at 0xc

Thread 0 Crashed:
0 0x1000 + 457016
…

    I'll attach the preprocessed source.  It was copied by Rob Stevenson, a former PalmSource employee, 
from volume one of Bruce Eckel's _Thinking in C++_.  Here's the relevant function:

string FramisTest() {
   	stringstream ss2;
  Framis* f[Framis::psize];
  try {
    for(int i = 0; i < Framis::psize; i++)
      f[i] = new Framis;
    new Framis; // Out of memory
  } catch(bad_alloc) {
    ss2 << "Out of memory!" << endl;
  }
  delete f[10];
  f[10] = 0;
  // Use released memory:
  Framis* x = new Framis;
  delete x;
  for(int j = 0; j < Framis::psize; j++)	{
  	ss2 << f[j]->ReturnStrStream() ;
    delete f[j]; // Delete f[10] OK
   }
  return ss2.str() ;
} ///:~
