Unfortunately, the same test program also crashes when built and linked on OSX.

I tested with Sierra (OSX 10.12.5), gcc 7.2.0, compiling the original sample
here with:

g++-7 -D_GLIBCXX_USE_CXX11_ABI=0 -std=c++17 -O1 test.cpp

Result:

> ./a.out
a.out(608,0x7fffbda8a3c0) malloc: *** error for object 0x10c68d080: pointer
being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6


I think this means the Darwin linker has a similar problem.
