Were you using your N10? On my N4 it seems to work (both root and non-root). Also MOZ_LINKER_ONDEMAND shouldn't be needed in most cases with recent versions of JimDB.

This was on my N4. If I run without MOZ_LINKERD_ONDEMAND I still get SIGSEGVs everywhere and have to do the "handle sigsegv nostop noprint" thing to make it usable. It might be that I just need to rebuild jimdb from the latest source again. I'll kick that off and let you know.

Hm. I rebuilt gdb and updated my utils folder and still get the same behaviour. I also see the behaviour if I just try to run bin/gdb and choose option 1, which is weird. Maybe this is wonkiness with android 4.3. I don't remember if I updated to 4.3 before or after I filed this bug.

After some debugging over IRC it turns out this is because I wasn't properly rooted. Using TWRP and SuperSU 1.65 got me a good root shell and this problem went away.
