Hi,

Please unblock package sbc 1.3-2 as it fixes a RC bug
(Closes: 856487).
This fixes the problem that libsbc crashes on armhf.
This is a problem with ARM's assembler. This fix avoids
the problem by not using the ARM assembler, and using C
implementation.

unblock sbc/1.3-2

+  * Disable the ARMv6 asm implementation. (Closes: #856487)
+     This gets miscompiled with recent gcc since gcc does not consider
+     r3 clobbered by the basic asm in a naked function (see #856487).
+     The imost simple short-term fix is to disable the ARMv6 asm
+     implementation on armhf and use the C implementation instead.
+     Thanks to Adrian Bunk <b...@debian.org> and bug reporters.

+Subject: [PATCH] Add config.h in sbc/sbc_primitives.h
+
+When we use "--enable-high-precision" option of configure, this does not work
+effectively. Because SBC_HIGH_PRECISION enabled by this option is not available
+in "sbc/sbc_primitives.h".
+This adds config.h to "sbc/sbc_primitives.h" to use SBC_HIGH_PRECISION.
