Thanks for the report. Pushed 9.0.1-2 RPMS which fix this problem:

# eu-unstrip -n -e /usr/proj90/lib64/libproj.so.25.9.0.1
0+0x609ca0 5eb27c936540bd4d5b9e43e9095ba8315580232f(at)0x248 /usr/proj90/lib64/libproj.so.25.9.0.1 /usr/lib/debug/usr/proj90/lib64/libproj.so.25.9.0.1-9.0.1-2.rhel8.x86_64.debug

# eu-unstrip -n -e /usr/lib/debug/usr/proj90/lib64/libproj.so.25.9.0.1-9.0.1-2.rhel8.x86_64.debug
