Replying to [comment:7 bonefish]:
> Unless there's a good reason to do that -- like both sections containing
different parts of the information -- I wouldn't do that. I wonder anyway
why the .debug_frame is no longer correctly written. After all it is
documented to contain the information. Have you read anything about this
(e.g. in the changelog, some announcement, or discussion)? Or might this
just be a bug?
I'd guess bug, but I haven't had a chance to go through the mailing lists
and announcements to find anything yet. For now I simply changed it as I
did so we'd adapt to whatever the current situation happens to be.
> Or do that lazily/cache information. The startup already takes quite
some time and doing more preprocessing will make that even worse. Although
that's probably quite a bit of work, it might be necessary to preload even
less information (load the CIEs on demand with caching). I may recall that
incorrectly, but didn't debugging WebPositive (with full debug info for
WebKit) even hit the address space limit?

We do indeed have that problem, though gdb does as well iirc. If memory
serves, we actually hit the issue up front while parsing the DIEs though,
would need to try again to see. In any case, will file an enhancement
ticket for lazy evaluation/loading.
