Subject: [Bug c++/18024] New: IOT/Abort trap (core dumped) on AIX with -pthread

I'm running on a 32-bit AIX 5.1 box.  GCC 3.3.5 was configured as follows and 
bootstrapped.

# This directory was configured as follows:
/home/downloads/gcc/gcc-3.3.5/configure --with-gcc-version-trigger=/home/downloa
ds/gcc/gcc-3.3.5/gcc/version.c --host=powerpc-ibm-aix5.1.0.0 --enable-threads=po
six --prefix=/usr/local/gcc/gcc-3.3.5 --enable-languages=c,c++ --norecursion

When I compile any program that uses -pthread and also throws exceptions, 
an "IOT/Abort trap (core dumped)" occurs.

To reproduce this bug, use the following program.

FILE: main.cpp (begin)

int
main(int argc, char** argv)
{
  try
  {
    throw "bug";
  }
  catch(...)
  {
  }

  return 0;
}

FILE: main.cpp (end)

* When compiled with "g++ main.cpp" the application runs fine.  
* When compiled with "g++ -pthread main.cpp" the error occurs at runtime.  
* When compiled with "g++ -lpthread main.cpp" the application runs fine.  
However, this does not link libgcc_s_pthread which leads to instability in the 
real threaded application.

This bug is similiar to #13391, but 3.3.5 did not contain the patches 
referenced.
