This was due to the 'assert' macro expanding into a function call on some platforms which could throw. The C++ compiler then added checks for the exception specifications in these functions, which pulled in the C++ runtime. This was bad, and the assertions can never fire (the library is now debugged) so just remove them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9801 91177308-0d34-0410-b5e6-96231b3b80d8
