The original breakpoint location test was failing for linux, because the
compilers here tend to
merge the full-object and subobject destructors even at -O0 (as a result, we
are getting only 2
breakpoint locations, and not 4 as the test expected. The fixup in r266164
substantially weakened
the test, as it now did not check whether both kinds of destructors were being
found.
Because of these contraints, I have altered the logic of the test. It sets the
breakpoint by name, and then independently verifies that the breakpoint is set
on the correct
demangled symbol name (which is not very meaningful since both kinds of
destructors demangle to
the same name) *and* the correct symbol address (which is obtained by looking
up the mangled
symbol name).
