Previously we'd try to perform checks on the captures from the middle of parsing the lambda's body, at the point where we detected that a variable needed to be captured. This was wrong in a number of subtle ways. In PR23334, we couldn't correctly handle the list of potential odr-uses resulting from the capture, and our attempt to recover from that resulted in a use-after-free. We now defer building the initialization expression until we leave the lambda body and return to the enclosing context, where the initialization does the right thing. This patch only covers lambda-expressions, but we should apply the same change to blocks and captured statements too. llvm-svn: 235921
