I want to collect which GCC version are used by you. Now, I use GCC 5.5 for the verification. It may be a little old. I use multiple GCC* toolchains, with different frequencies. My primary work laptop runs RHEL7, so I most frequently build (for IA32/X64) with GCC48: > gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) Whenever I build on RHEL8, I use gcc-8. On occasion, I might build on recent Fedora (gcc-9 I guess), but that's quite exceptional for me. Thanks, Laszlo
