GCC g++ version 8 very slow to compile

With the latest gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2 compiler tools release, g++ is very slow to compile relative to the older gcc-arm-none-eabi-7-2017-q4-major-linux.tar.bz2 release.

I am seeing it take over 3 times longer than the previous compiler. A previously 45 second build now takes 2.5 minutes.

Is this to be expected ?

Are there any compiler flags that will speed this up (less optimisations) as it is now taking a significant time to build things ?

Any news on this issue ? Is there anything I can do to help track down the problem assuming there is one and it's not due to an extra optimisation stage/stages ?
