## If the e_shoff field is set to a value either past the end of the file, or

## such that e_shoff + e_shnum * sizeof(Elf_Shdr) is past the end of the file,
|
||
|
|
## we should emit an error. This test checks that the emitted error is sensible.

## Truncate the file to end before the section header table ends.
