I constantly worry about size limitations, but here is my config and
the complete segfaulting log

I will look into pthread_initialize.
locale is enabled

What i am seeing on the patch is that the non-segfaulting version
calls _dl_get_ready_to_run:814: calling INIT: /lib/libintl.so.8 before
libpthread.

Another thing that sticks out to me is that "_dl_fixup:664: relocation
processing: /lib/libpthread.so.0" happends in the non-segfaulting one,
but does appear in the segfaulting one.

And finally there is the part you mentioned about pthread.

Those things stood out to me in the diff, i will look into commenting
out pthread_initialize()
