Hello,

I was trying to debug some code today and noticed that the CRC
contained in
proj90-9.0.1-1.rhel8 does no match the CRC in the debuginfo package
proj90-debuginfo-9.0.1-1.rhel8.

GDB returned the following error when loading my executable:

warning: the debug information found in
"/usr/lib/debug//usr/proj90/lib64/libproj.so.25.9.0.1-9.0.1-
1.rhel8.x86_64.debug"
does not match "/usr/proj90/lib64/libproj.so.25" (CRC mismatch).

warning: the debug information found in
"/usr/lib/debug//usr/proj90/lib64/libproj.so.25.9.0.1-9.0.1-
1.rhel8.x86_64.debug"
does not match "/usr/proj90/lib64/libproj.so.25" (CRC mismatch).

To confirm, i ran the following:
$ eu-unstrip -n -e
/usr/lib/debug/usr/proj90/lib64/libproj.so.25.9.0.1-9.0.1-
1.rhel8.x86_64.debug

/usr/lib/debug/usr/proj90/lib64/libproj.so.25.9.0.1-9.0.1-
1.rhel8.x86_64.debug
.

$ eu-unstrip -n -e /usr/proj90/lib64/libproj.so.25.9.0.1
0+0x609ca0 5425059ada9e996f4bd0fcc87514249af65af370@0x248
/usr/proj90/lib64/libproj.so.25.9.0.1 -

You can see the second field containing the CRC does not match

I downgraded to proj90-9.0.0 and the CRC's match each other.

$ eu-unstrip -n -e
/usr/lib/debug/usr/proj90/lib64/libproj.so.25.9.0.0-9.0.0-
1.rhel8.x86_64.debug

/usr/lib/debug/usr/proj90/lib64/libproj.so.25.9.0.0-9.0.0-
1.rhel8.x86_64.debug
.

$ eu-unstrip -n -e libproj.so.25.9.0.0
0+0x603c80 f18f4e8a60f04874716f1afdebf919db18939bce@0x248
/usr/proj90/lib64/libproj.so.25.9.0.0
/usr/lib/debug/usr/proj90/lib64/libproj.so.25.9.0.0-9.0.0-
1.rhel8.x86_64.debug

You can also see that `eu-unstrip` finds the matching debug info in
this
case, it did not find it above for proj90-9.0.1.

Can you please check on this and look into a potential fix?

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