Nonsense. lyxbreaker calls BOOST_ASSERT which calls assertion_failed
(src/boost.C) which calls emergencyCleanup which saves your data.

Yes. Fix the underlying bug which is whatever lead to the assert in the
first place.
Ie, André is saying that the execution path looks like:
CoordCacheBase::check(some stuff) {
if (some stuff is invalid)
lyxbreaker(some stuff);
}
Which means that it's dead easy to set a break point in gdb. Any entry
into lyxbreaker is automatically invalid, so stop there and have a look at
the execution path to that point.
Try it yourself:
gdb ./lyx
(gdb) break lyxbreaker
Breakpoint 1 at 0x120132a34: file ostream, line 193.
(gdb) run
Make it crash and now type
(gdb) where
(gdb) backtrace
