Comment #44 on issue 2801 by [email protected]: Patch: Approximates cross-staff
slurs in VerticalAxisGroup vertical-skylines.

Regarding comment #42: if anything makes it into the skyline, there should
be references to it, so it should be safe from garbage collection as long
as those references exist and are properly marked during the marking phase
of the garbage collector. Of course, assuming that all your data
structures keeping references properly mark them (via derived_mark and
relatives). So garbage collection itself should not pose a problem as long
as the code is clean.
If you want a recompilation with significantly different memory layout,
reconfiguring with
-fkeep-inline-functions
is a pretty solid candidate for making quite a different executable (also
one more useful under gdb). Should be a good candidate for triggering
compilation-dependent flukes when compared to an executable without that
option.
