I was investigating what keeps glibc-32bit installed on my x86_64 system, and
stumbled about this:

strolchi:~ # rpm -e glibc-32bit 2>&1|grep mumble
        libc.so.6 is needed by (installed) mumble-1.4.230-1.3.x86_64
        libc.so.6(GLIBC_2.0) is needed by (installed) mumble-1.4.230-1.3.x86_64
        libc.so.6(GLIBC_2.1.3) is needed by (installed)
mumble-1.4.230-1.3.x86_64
        libc.so.6(GLIBC_2.28) is needed by (installed)
mumble-1.4.230-1.3.x86_64
        libc.so.6(GLIBC_2.3.4) is needed by (installed)
mumble-1.4.230-1.3.x86_64
        libc.so.6(GLIBC_2.33) is needed by (installed)
mumble-1.4.230-1.3.x86_64
        libc.so.6(GLIBC_2.34) is needed by (installed)
mumble-1.4.230-1.3.x86_64
        libc.so.6(GLIBC_2.4) is needed by (installed) mumble-1.4.230-1.3.x86_64
strolchi:~ # rpm -q --requires mumble|grep -v 64bit
/bin/bash
libc.so.6
libc.so.6(GLIBC_2.0)
libc.so.6(GLIBC_2.1.3)
libc.so.6(GLIBC_2.28)
libc.so.6(GLIBC_2.3.4)
libc.so.6(GLIBC_2.33)
libc.so.6(GLIBC_2.34)
libc.so.6(GLIBC_2.4)
...

This looks wrong.
