There was an issue in badger and has been recently fixed. Unfortunately, the recent fix wasn't quite correct. The new fix is at dgraph-io/badger#378. Once that gets merged, we'll bubble it up to here.

• issue building ipfs for ios #4210 has been fixed (forgot to close it).
• We have no information on that crashing issue so we can't really debug it. It may have already been fixed, for all we know (it has been a year).
• With regards to the android issue, I believe the reporter was trying to use go-ipfs as a library.

Thanks @Stebalien - just mentioned those others for your reference in case they were helpful in resolving this one.

@magik6k this has now been fixed in badger. Mind updating go-ds-badger?

[magik6k]

So you can now close issues cross-repo, fun.. Keeping this open until it's in merged to master.

@Stebalien mind including this in #4610?

[Stebalien]

@magik6k done.
