change was fixed.
* Christoph Müllner has contributed couple warnings fixes and
initial support for aarch64_ilp32 architecture.
* Ben Dang contributed documentation fix for heap checker.
* Fabrice Fontaine contributed fixed for linking benchmarks
with --disable-static.
* Holy Wu has added sized deallocation unit tests.

Subject: [PATCH] Include asm/ptrace.h when accessing ucontext_t
|
|
|
|
In some architectures (e.g. powerpc, powerpc64 and powerpc64le), the
|
|
macro that specifies the position of the program counter is defined in
|
|
header asm/ptrace.h.
|
|
|
|
When glibc bug 21457 got fixed in version 2.27, header sys/ucontext.h
|
|
stopped including signal.h, which indirectly removed asm/ptrace.h too.
