 Funny you should say this, I thought using these "magic" constants would
be too confusing for the beginners. Maybe I was wrong.

 I don't think there are any bugs in the code which can result in a crash
in such simple example so I suspect the libraries were built incorrectly
somehow and/or there was a mismatch between library headers and actual
libraries used.

 Are you sure the packages were built with the same compiler version or at
least a compatible one?

 Also, seeing you have the debug info package, what about running the
program under gdb and looking at the backtrace ("bt" command) when it
crashes?
