Comment #44 on issue 2801 by address@hidden: 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.
