                        42: R_386_TLS_IE_32     E


The error is in every other line.
For the R_386_PLT32 relocation with addend, I would have expected "b8 fd ff ff
ff".
For the other ones, I would have expected "b8 01 00 00 00".

There might be other relocations with this issue; I don't know all the
relocation types.
