I'm trying to use `boost::exception` and have condensed my prototype
code down to the example in the Boost exception tutorial
(http://www.boost.org/doc/libs/1_47_0/libs/exception/doc/tutorial_transportin...)
however when running the code with the `BOOST_THROW_EXCEPTION` macro I
get an abort from the program.
#include <iostream>
#include
typedef boost::error_info my_info;
struct my_error: virtual boost::exception, virtual std::exception { };
void f() {
BOOST_THROW_EXCEPTION(my_error() << my_info(42));
// Uncomment the below (and comment the above) for the program to work
//throw my_error() << my_info(42);
}
int main(int argc, char** argv) {
try {
f();
}
catch(my_error& x) {
if(int const* mi = boost::get_error_info(x)) {
std::cout << "My info: " << *mi << std::endl;
}
}
return 0;
}
Running the code with the BOOST_THROW_EXCEPTION macro:
$ ./a.out
Abort trap
If as the comment says, I swap the code, all is well
$ ./a.out
My info: 42
Below is the output from the g++ preprocessor for f()
void f() {
::boost::exception_detail::throw_exception_(my_error() <<
my_info(42),__PRETTY_FUNCTION__,"main.cpp",14);
}
Software versions are:
$ g++ -v
Using built-in specs.
Target: x86_64-apple-darwin10
Thread model: posix
gcc version 4.4.6 (GCC)
$ port list boost
boost @1.47.0 devel/boost
I'm on OSX SL using the tools provided by MacPorts. I've double checked
the g++ search paths and there's only one copy of the boost hpp files
and that's the ones that belong to the aforementioned boost package.
I have no idea why the abort trap is being called. I admit I'm newish
to C++.
I've also asked this question on StackOverflow

Cheers,
