Package: libc6
Version: 2.1.1-12.1
Severity: normal
Apologies if I sent this twice - I think my first try didn't go through.
Attached is an NMU patch to get glibc to work on ARM.
Cheers,
- Jim

+Hi,
+
+This patch corrects a long-standing problem that caused ld.so to segfault when
+glibc was compiled with -O2 or higher on the ARM. The old code relied on
+addressing the GOT from inside the asm, but because the compiler couldn't
+see this it was tending to reschedule instructions so that the PIC register
+wasn't loaded until later in the function.
+
+Uli, could you check this in please? It should probably go into the glibc 2.1
+branch as well as the mainline.
+
+Thanks
+
+p.
