Update to 5.2.026-3 breaks builtin printf behaviour

Description:

After the update to 5.2.026-3 builtin printf is misbehaving.

Before:

# bash -c 'printf "%.0f\n" 4.3'
4

After:

# bash -c 'printf "%.0f\n" 4.3'
nan

Additional info:

• package version(s): 5.2.026-3
• Downgrading to 5.2.026-2 fixes the issue
• Calling /usr/bin/printf(to ignore bash builtin) instead returns the correct result (in any of the 2 releases)

Steps to reproduce:

• Upgrade bash to 5.2.026-3
• In a new session call printf "%.0f\n" 4.3.
• Expected result: 4. Gets 'nan' or '-nan'
