sjsl exceptions is one way to implement exception handling. On most
systems, we have moved to more efficient ways, such as dwarf2
unwinding. However, if you don't use exceptions, trying things out
with -fno-exceptions may be an interesting experiment anyway.
Regarding the times not adding up: I think this is usual for gprof. In
fact, gprof is not a very good tool anyway, but it is the one that is
most widely available. There are more accurate ones, which I have never
used myself, though, so I can't say anything about them. I think I
remember people being quite fond of oprof. It may also be the case
that valgrind can produce some sort of information, but I don't know about
that exactly.
