[Galaxy S III Original Android Development] forkbomb444:
segfaults! they're everywhere.

I booted into L without gapps, and then flashed the gapps. It gets to "Starting apps." and does this over and over:

If you're having bootloops after flashing gapps you should probably follow the instructions in this post

Great work though! Keep it up :)

EDIT: I found the issue. The libspeexresampler.so provided in the gapps doesn't play nice with the rest of the ROM. Simply back up /system/lib/libspeexresampler.so before flashing gapps and then put it back where it was afterwards (make sure to mount /system in recovery both before and after flashing gapps!). Note that this seems to break the Google TTS Engine, it FC'd a few times on startup for me. But everything works now (minus the things listed as not working in OP, of course.)
