as you can see the &u at bar differs between ctor/test for clang. looks like a
bug.

% ./build-gcc && ./m  
&foo
ST::ctor(this = 0x1a0a280, &u = 0x7ffb6911c038)
ST::test(this = 0x1a0a280, &u = 0x7ffb6911c038)
&bar
ST::ctor(this = 0x1a0a2a0, &u = 0x7ffb69119038)
ST::test(this = 0x1a0a2a0, &u = 0x7ffb69119038)

% ./build-clang && ./m
&foo
ST::ctor(this = 0x11bd280, &u = 0x7f6d980f0020)
ST::test(this = 0x11bd280, &u = 0x7f6d980f0020)
&bar
ST::ctor(this = 0x11bd2a0, &u = 0x7f6d980ed020)
ST::test(this = 0x11bd2a0, &u = 0x7f6d980f0020)

tested @ fedora-27 with system-wide compilers:

% rpm -q gcc clang
gcc-7.2.1-2.fc27.x86_64
clang-5.0.1-1.fc27.x86_64
