Subject: [glibc] Change _IO_stderr_/_IO_stdin_/_IO_stdout to compat symbols [BZ #31766]
Date: Tue, 21 May 2024 17:12:40 +0000 (GMT)	[thread overview]
Message-ID: <20240521171240.B9A173858C66@sourceware.org> (raw)

https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=85472c20a55ea2a49a7fbdf71652b4009118b0ae

commit 85472c20a55ea2a49a7fbdf71652b4009118b0ae
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Mon May 20 19:30:58 2024 -0700

    Change _IO_stderr_/_IO_stdin_/_IO_stdout to compat symbols [BZ #31766]
    
    Since Glibc never provides symbol binary compatibility for relocatable
    files, fix BZ #31766 by changing _IO_stderr_/_IO_stdin_/_IO_stdout to
    compat symbols.
