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.

../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

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() ;
} ///:~
