Description:
Yonghong Song brought a story about tracking down the cause of a strange 
verifier error

Summit. He then presented some possible ways to improve Clang's user 
experience for
anyone running into the same class of error in the future. Toward the end of 
his
allotted time, he also discussed the problems with optimizations that change 
the
signature of functions  a problem that Jos Marchesi had also brought up in 
the previous session .
