Ping? Any progress on this one? Many thanks, John Maddock.

Gennadiy,

Would you know the likely reason for a boost::system_error being thrown in this test: http://tinyurl.com/yq2yya ?

Glancing at the Boost.Test source this appears to be thrown when an internal Boost.Test assertion fails? Any ideas what's going on?

system_error is thrown in case if system level call failed. I am on vacation till the end of the week. I will try to look at this Sunday.

Thanks Gennadiy: have a good vacation!

The link now shows boost::thread_resource_error as a thrown exception. I am afraid I would have problems figuring this out even if it was boost.test exception. I need an access to the platform to debug it. The only thing I can tell immediately is that system_error is caught by execution_monitor itself (see line ~ execution_monitor.ipp:1110). So it should be some strange combination of events to produce system_error from execution monitor invocation

Yep, these exceptions seem to be comming and going, which is rather frustrating to say the least. Currently this one: http://tinyurl.com/3xx3o7 is showing: terminate called after throwing an instance of 'boost::system_error' EXIT STATUS: 134 So the exception is raised even before cpp_main is entered and before execution monitor's own try...catch blocks are entered I assume? Noel: I don't suppose you have a couple of spare minutes to find out where this exception is comming from? Many thanks, John Maddock.

I've been getting the same problem - the following code reproduces it on an Intel mac: // Copyright 2007 Jeremy Pack // All rights reserved #define BOOST_TEST_MAIN #define BOOST_TEST_DYN_LINK 1 #include <boost/test/unit_test.hpp> #include <iostream> // #include "../src/paf_ged_loader.hpp" // #include "../src/repository.hpp" #include <boost/regex.hpp> BOOST_AUTO_TEST_CASE(regex) { boost::regex i("test"); std::string s("test"); boost::smatch match; boost::regex_match(s, match, i); } The system_error seems to be thrown at the call to regex_match. However, if I add the header #include <boost/test/execution_monitor.hpp>, the problems disappear. I've tested this in multiple files. It always dies on regex_match, unless I include boost/test/execution_monitor.hpp. Jeremy Pack On Nov 23, 2007 6:59 AM, Gennadiy Rozental <rogeeff@gmail.com> wrote:

Yes.

Here are all the places where syste error may've come from:

execution_monitor.ipp(532): BOOST_TEST_SYS_ASSERT( ::sigaction( m_sig , sigaction_ptr(), &m_new_action ) != -1 ); execution_monitor.ipp(542): BOOST_TEST_SYS_ASSERT( sigemptyset( &m_new_action.sa_mask ) != -1 ); execution_monitor.ipp(549): BOOST_TEST_SYS_ASSERT( ::sigaction( m_sig, &m_new_action, &m_old_action ) != -1 ); execution_monitor.ipp(642): BOOST_TEST_SYS_ASSERT( ::sigaltstack( 0, &sigstk ) != -1 ); execution_monitor.ipp(648): BOOST_TEST_SYS_ASSERT( ::sigaltstack( &sigstk, 0 ) != -1 ); execution_monitor.ipp(667): BOOST_TEST_SYS_ASSERT( ::sigaltstack( &sigstk, 0 ) != -1 ); execution_monitor.ipp(696): BOOST_TEST_SYS_ASSERT( ::signal( sig, SIG_DFL ) != SIG_ERR );

What you can do is to try catch the exception in your code and report it yourself. This may at least show some information. I guess I should also include failed expression text. It's not there yet.

BOOST_AUTO_TEST_CASE(regex) { boost::regex i("test"); std::string s("test"); boost::smatch match; boost::regex_match(s, match, i); }

The system_error seems to be thrown at the call to regex_match.

This is very strange - especially as regex makes no use of Boost.Test internally - I don't see how a call into the regex lib can result in Boost.Test throwing ! Are you able to trap the point at which the exception is thrown (gdb has an option to break on a throw exception I believe): what we really need to determine is the code that triggers this. Many thanks, John Maddock.
