Boost Python seems to be failing to catch and translate C++ exceptions
for me on a BlueGene/P installation. I really don't know what to do next
in debugging the problem, so I would appreciate any advice.
I have a simple test module, pyexcept
------------------------------------------------------------
#include <boost/python.hpp>
#include <iostream>
#include <stdexcept>
void
foo()
{
std::cout << "in foo, about to raise exception\n";
throw std::runtime_error("runtime_error from foo");
std::cout << "this should never be seen\n";
}
using namespace boost::python;
BOOST_PYTHON_MODULE(pyexcept)
{
def("foo",foo);
}
------------------------------------------------------------
I test it with the following python script:
------------------------------------------------------------
#!/usr/bin/env python
import pyexcept
print "about to run pyexcept.foo, catching exception"
try:
pyexcept.foo()
except RuntimeError,e:
print "caught RuntimeError,",e
------------------------------------------------------------
On my Linux machine I see:
------------------------------------------------------------
about to run pyexcept.foo, catching exception
in foo, about to raise exception
caught RuntimeError, runtime_error from foo
------------------------------------------------------------
On the BlueGene/P machine I see:
------------------------------------------------------------
about to run pyexcept.foo, catching exception
in foo, about to raise exception
terminate called after throwing an instance of 'std::runtime_error'
what(): runtime_error from foo
------------------------------------------------------------
I have (cross-)compiled boost myself using the system's installed
version of the gnu compilers, 4.1.2:
------------------------------------------------------------
|login2>mpicxx.gnu --version
powerpc-bgp-linux-g++ (GCC) 4.1.2 (BGP)
------------------------------------------------------------
(The mpicxx.gnu script is a wrapper around the cross-compiling g++.) Has
anyone seen a problem like this? Any ideas as to how to debug it?
Thanks for any advice.
