This has been once reported, but was considered to be the same as bug 19667,
after the fix, I still encounter the same problem. Following steps can
reproduce the problem:
using msvc2013 x64 environment to build the llvm/clang trunk and then:
vcvars.bat //for x64 msvc tools env such as link.exe
llvm-as b.ll
clang b.bc
then ms link.exe complains:
b-1e6a24.o : fatal error LNK1223: invalid or corrupt file: file contains
invalid .pdata contributions
clang.exe: error: linker command failed with exit code 1223 (use -v to see
invocation)
see attachment for sample file.
