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

[askees at appfluent dot com]

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.

Yes 3.3.5 did not contained the patches, could you try 3.4.0 then?

Thanks for the quick response!!

I've not been able to install 3.4.2 on my system.  I keep running into the
"cannot run 64-bit applications on 32-bit machines" error during
bootstrapping.  I was actually just trying 3.4.2 one last time with an extra
"--disable-aix64" option and then planned on submitting a bug for that one
too!

Is the patch available for 3.3.5?

After many attempts with various configure settings, I was able to get 3.4.2 
(with both libstdc++-v3 and libgcc_s_pthread) installed.  As in 3.3.5, the 
problem still exists if both libpthread (in /usr/lib/libpthreads.a) and 
libgcc_s_pthread are linked.   

If I explicitly remove libgcc_s_pthread, the core does not occur.  However, 
this library is linked automatically by the -pthread option, so I assume it is 
important and required.

As a side note, I tried the example code in bug #13391 and those test cases are 
broken as well.
