Hello all,

Recently, I have found that with GCC version bump in F36 some of my packages are stopped to build, or stopped to build properly during the planned package rebuild.

They were fine under F35 — but apparently there are some changes in newer GCC that affected them.

For example, "libscrypt" package issue is filled here: https://bugzilla.redhat.com/show_bug.cgi?id=2046062

The library in the package was actually built, but the build results are different under various GCC versions — as shown in the "nm" dump below.

Has anybody already faced a similar issue? Is there any information on what could cause the problem, and how to fix it?

Thanks!
