IMHO we really do need a small re-think here; the primary use-case I was aware of for libmerged is to enable more LTO, and faster start-up. I rather suspect that merging all the components: base, writer, calc etc. into the libmerged may not help startup on lots of hardware; so I'm curious as to the plan there. If we break the unit tests by doing that, almost certainly we'll break the run-time functionality too :-) so - prolly rather better to back that stuff out until it works. So I'll merge this: https://gerrit.libreoffice.org/3280 Peter - any chance of tweaking your use-case to include those libraries that you want merged in there (assuming you do) conditionally with a non-default configure switch as Matus suggests ? I believe Matus is trying to get this into a more reliable and ship-able state for Raspberry Pi, so until we've nailed the regressions and thought this through some more, I'd prefer to take a step back and re-think if that's ok ? Peter - did you get any further with the graphics filters ? at some stage, I suspect that they are doing some oslLoadModule to load the graphics driver pieces - that might be going wrong. If there is some symbol overlap problem, you could try to find that like this: for a in *.so; do echo $a ; readelf -s $a --wide | grep -v UND | cut -c52-; done > /tmp/symbols.txt sort /tmp/symbols.txt | uniq -c | sort -n | less I'd start by using readelf --dyn-syms perhaps and then use -s if that fails; of course you want to reverse grep _ZThn and _ZTV etc. and manually ignore inlined methods which are expected to be duplicated but are hopefully the same everywhere (due to the ODR). Beyond that - debugging, and careful unwinding back to what is going wrong with image load/export would be good - I'd use gdb to see where your pointer got corrupted (IIRC I gave some pointers to that in the past on the list?).
