Re: [Boost-users] Threads, FunctionPtr and stepping through code

Thanks for the advice :) My gut feeling told me that my problem is in the xcode project settings since the code works fine on the Intel version of Mac OS, works fine as an application on PowerPC but fails when used on the PowerPC processor. Like your experience, I feel that this is something that is going to take me a while to figure out since I didn't start the project and it has a long history behind it. Thanks again and if there is anything else you, or anyone else, can think of, I'm all ears! Thanks again! -Jaime On 8/7/07, Chris Uzdavinis wrote:

After spending many hours trying to find out what the cause of the problem is, the only thing I could derive was that the address that Boost was using to access my function was wrong. Before the error, I have the following address to my function:

I'm not sure if this helps, but in a different context unrelated to Boost, we ran into a case where addresses seemed to randomly change. After hours and hours of debugging, we decided it was the compiler generating code strangely. In the end, we discovered that the build options for the shared library differed from the main executable in such a way as to affect the binary object layout. When an object was passed across the boundary (from the executable to a library function), addresses "shifted" since functions in the library did different offset calculations to find members, etc. Perhaps you could review your build options to ensure it's not something along those lines. Fixing our makefile and recompiling solved the bug for us. (It has been years now, but it's the kind of bug I will never forget.)
