So, Peter said for the next LTS (2020.02), we probably want to have
removed the oldest gcc versions (4.9, 5 and 6, most likely).

I think we should also drop it. I was keeping it because it was the
last gdb version that could be built with a toolchain that doesn't have
C++11 support. But well, C++11 is there since gcc 4.8, so let's assume
most sane people have moved their distribution to a version that has
gcc 4.8 at least.

So on my side, green light to drop gdb 7.12.

Best regards,

Thomas
