--- Comment #4 from Benjamin Buch ---
I can still reproduce it on R257659:
$ g++ -std=c++14 main.cpp
main.cpp: In instantiation of 'foo(T ...) [with T = {int}]:: [with auto:1 = {int}]':
main.cpp:9:6: required from 'void foo(T ...) [with T = {int}]'
main.cpp:13:10: required from here
main.cpp:8:17: error: use of 'bar' before deduction of 'auto'
sink(bar(v, T{}) ...);

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84368 --- Comment #3 from Benjamin Buch --- I'm on git commit a5283f322810189a156a0fb080bf6d65e6f7970e which should be R257627. I used: $ git svn find-rev $(git log --max-count 1 --pretty=format:%H) Migrating from a git-svn v1 layout... Data from a previous version of git-svn exists, but .git/svn (required for this version (2.7.4) of git-svn) does not exist. Done migrating from a git-svn v1 layout 257627 Hope this is the correct way to get the revision number. I will check if I can reproduce it with current trunk again.

Wonder if the order of instantiation of pending templates isn't depending on some unstable sort or something similar, this is a second PR in a short time where it can't be reproduced in all compilers I have around.

Before that it just ICEd, starting with r251433. Before that it has been accepted too.
