Unfortunately it doesn't:

$ ../TestRunner.sh struct.c
******************** TEST 'struct.c' FAILED! ********************
Command:
  clang struct.c -emit-llvm
Incorrect Output:
Assertion failed: (CGT.getTargetData().getABITypeSizeInBits(STy) ==  
RL.getSize()), function layoutStructFields, file CodeGenTypes.cpp,  
line 531.

Is there any particular information you need to debug this?  I'm not  
very familiar with the Codegen module.
