At boot init fails directly=20=20 and=20I get asked which shell I want. /bin/sh dies directly too and I=20=20 get=20asked which shell I want again. With the r342714-BE booted and mounting the r343917-BE somewhere I can=20= =20 start=20the new sh on the old system without issues. If I compare the objdump -x output of init (oldnew): for the old one=20=20 there=20is an invalid relocation type 37 reported, and for the new one=20= =20 there=20is at the end of objdump an additional relocation record for=20=20 .got.plt.=20The rest of the difference is just different offsets and=20=20 sizes. The=20file util doesn't report anything different for init. This is after deleting /usr/obj, and cleaning the ccache cache. All=20=20 cases=20are with CPUTYPE=3Dnative (Intel Xeon E5620). I remember a commit of a new clang to head. Anything else in the area=20=20 of=20influence for this? My next try is to compile without CPUTYPE=3Dnative to see if the new=20=20 clang=20is doing something in this area which it didn't do before. Has=20= =20 anyone=20else seen a similar issue or has an idea what to look at next?
