I use this version on a bare metal centos 7 + devtoolset-9 system with 32 Gb ram I have never experienced segfaults during the make menuconfig step.
You can try a "strace -v -f -ff -y -s 1024 -o tracefile make menuconfig" and grep SIGSEGV tracefile* this will tell you at least which process fails and why.
"make V=sc menuconfig" may also help.
Edit: the SIGSEGV appears to come from gcc, use Ubuntu 20.04 istead.
