RE: Debugging C++ problem
On Linux/X86 you should be able to build the collector with -DSAVE_CALL_COUNT=8 (or
--enable-full-debug). This will save partial stack traces in each object. In the most recent versions of
the collector, diagnostic routines should print this in human-readable form, assuming you compile with
-g and have addr2line available.
For this to work, don't compile with -fomit-frame-pointer. The stack saving code relies on the frame pointer.
Unfortunately, this varies depending on the hardware platform, since stack unwinding ease/facilities
vary. (In the most recent version, with gcc, either -DAVE_CALL_COUNT should work, or you should get one
additional return address automatically, using gcc's __builtin_return_address(0).)
