Hey everyone,
Hi Chad, I'm sorry for lond delay. I did not forget about you. I've been a bit busy with boostcon.
I'm new to the Boost libraries but *love* everything I've seen so far.
I am having some trouble running my code on OS X.
Unfortunately I do not have access to this platform.
Up until today I've been working in CentOS 4 on an older PIII server. I moved my code over to my Intel Mac workstation so I can use a fancier text editor (yea yea...). I made it through some linkage hurdles with Jam and everything compiled without issue. What happens now is I receive a Bus Error when running my unit tests. I've written a separate test app without using the Boost Unit Test Framework and I am error free.
Could you provide stack dump?
I would not be surprised if this was the result of my not quite understanding the caveats of the Boost testing framework. I am using boost version 1.33.1 from Darwin Ports.
Couls you please try to use 1.34.0?
I understand it might be tricky to provide feedback given I am not including all the source. I am fairly certain the issue I am having is with the testing framework and not my code BUT I will send it along if you want to take a look. It also appears that the test app fails *after* running the test cases:
---------- # echo "SELECT attribute_id from attributes where interface_name = 'Login';" | ./sql_parse_test Running 2 test cases...
-----1.38998 SELECT attribute_id from attributes where interface_name = 'Login'; SELECT : attributes Bus error ----------
Even when I pipe millions of SQL statements to the test it will not die until after it's finished. NOTE: The second test case is a function that spits out some timing information (all the timing code is crappy and temporary). Even without the timing output the error takes place after running the proper test cases.
GDB provides this tidbit: ---------- Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000000 0x00812b22 in boost::unit_test::framework::get () ----------

Thanks in advance, any feedback would be greatly appreciated.
Could you simplify an example to the minimal possible failing snippet? Gennadiy
