Subject: [Bug dynamic-link/31662] Stack not aligned at _start when calling ld.so explicitly
Date: Sun, 21 Apr 2024 10:55:04 +0000	[thread overview]
Message-ID: <bug-31662-131-kMl2Pxzr8R@http.sourceware.org/bugzilla/> (raw)

--- Comment #7 from Felix Potthast <mail@felix-potthast.de> ---
Yes, this is not occurring anymore since 2.36.
2.35 is still around, though. (Ubuntu 22.04 for example)

Do you have any plans on preventing this from occurring again?
This seems to have been unnoticed.

I would suggest removing the align from `sysdeps/x86_64/start.S`. (Lines 88,89)
It goes back to 2001 when the ABI didn't explicitly state the alignment at
process
entry. It shouldn't be needed anymore and just masks bugs like this.
