--- Comment #1 from Mike Gulick <mgulick at mathworks dot com> --- Just a minor update. I re-tested the reproducer on gcc 5.4 as well as 4.9.2, and the issue is present in both of those. I had originally thought the bug was not present in gcc 5.4 or earlier, however this is likely because the source code I was testing it on was not pushing the line map source location > 0x60000000 in these versions of the compiler.
