8650	Segmentation fault on x86 Linux with SSE2 intrinsics	andrey.zhdanoff@…	olli	"Modified coroutine/example/echo.cpp by adding function which using SSE2 intrinsic . Program built for x86 is seg-faulting due to miss-aligned stack. Build with:
g++ echosse.cpp -m32 -o echosse -O3 -g -I ../boost/boost_build/include/boost-1_53/ -Wl,libboost_context-gcc46-mt-s-1_53.a
GCC version tested: 4.6.2, 4.8.0.
Problem is in make_i386_sysv_elf_gas.S, line:
    leal   -0x8(%eax),     %edx         /* reserve space for the last frame on context stack; (ESP - 0x4) % 16 == 0 */
- apparently pasted from x64 version.
Changing to:
leal   -0x14(%eax),     %edx
fixed the problem for me."	Bugs	closed	To Be Determined	context	Boost 1.53.0	Problem	fixed		olli
