Ensure PT_GNU_EH_FRAME program header has non-zero size #17

Closed jryans closed 5 years ago

With Ubuntu 18.04, I appear to have libc debug info that has a PT_GNU_EH_FRAME program header, but with a file size 0, which I assume is invalid. Instead of crashing, this ignores the program header.

(So happy to see the green check from CI here!) 😄

In case you're curious, I am working up to a PR with CircleCI support in liballocs. This PR is some prep work for that.

Great -- thanks!
