Error reading line programs from binary compiled with gcc 11.2

[wheirman]

I'm getting the following error when reading line programs (readelf.py --debug-dump=decodedline) from a binary compiled with gcc 11.2.0 on Ubuntu 22.04:

ELF error: ('missing terminator', ArrayError('missing terminator', FieldError('expected 1, found 0',)))

The binary is attached here: fft.zip

I tried the code from #408 as well but that didn't help. readelf.py --debug-dump=info works fine on the same binary.

Confirmed, the issue exists, and it's unrelated to #408. The line program header format has been revised in DWARF5, we knew this was coming, now might as well be the time.

@wheirman: I have a fix in the works, #411. Mind if I make a test case for the future out of your binary? If not, let me know how did you build that binary (the compiler options) - I'll try and build something similar.

I'm not sure what the licensing is on that fft example. But a simple hello world gives the same error, you can use this one:
test-dwarf5-lineprogram.zip

This was compiled with just -g as an option.

Can you please verify that #411 fixes it (it landed on the master branch)?

Work fine! 👍

Closing this for now. Please reopen if you see it still doesn't work on the main branch
