My understanding of the problem is that the .text section has NOBITS, and __libelf_set_rawdata_wrlock() then doesn't read it, but then other code assume it was read, and gets bogus data. In relocate_section(), tdata->d_buf ends up being NULL, and from there on everything goes bad. I wonder why it keeps .text (and others) in the section headers and sets NOBITS instead of just removing the section from the file. I wonder if we need to add a NOBITS check at some higher level.
