It isn't a bug in mkmf.rb but in ruby core. Can you try more
recent version?

this is with the last stable snap*:

gcc -O3 -march=pentium3 -fomit-frame-pointer -s -pipe -I. -I. -c

can the problem depend from CFLAGS?

*i was unable to download the tarball form the official ftp, is it ok?.

gcc -O3 -march=pentium3 -fomit-frame-pointer -s -pipe -I. -I. -c

yes, try to remove -fomit-frame-pointer and if it's still crash give a
backtrace

without -fomit-frame-pointer all right.

Just a curiosity can you try it with --disable-frame-address, i.e.

CFLAGS="-O3 -march=pentium3 -fomit-frame-pointer" ./configure --disable-frame-address
