<pre>If you attempt to run llvm-objcopy on the object file produced by yaml2obj for
the below YAML, it crashes, when it should really just emit an error saying
that the program header is malformed.
Example yaml2obj input:
--- !ELF
FileHeader:
Class: ELFCLASS64
Data: ELFDATA2LSB
Type: ET_EXEC
Machine: EM_X86_64
Sections:
- Name: .foo
Type: SHT_PROGBITS
Size: 1
AddressAlign: 0x1000
ProgramHeaders:
- Type: PT_LOAD
FileSize: 0x100000
Sections:
- Section: .foo
C:\Work\TempWork> C:\llvm\build\Debug\bin\llvm-objcopy test.o test2.o
