[lldb-dev] Bad state of release 3.7.1?

[Pavel Labath via lldb-dev]

Hello Jeffrey,

we did test 3.7 before letting it out, bug this bug was fixed only
after the release date, so the fix is not present in 3.7. I think you
have a couple of options now:
- backport the patch to 3.7: should be pretty easy and I expect it to
"just work"
- llvm 3.7 + lldb 3.8: this won't work out of the box as llvm
interfaces have changed. I don't think it would be too hard to make it
work, but you would be in totally unsupported waters there..
- switch to lldb 3.8: probably the easiest solution. Note that you can
still use llvm 3.7 in other parts of your toolchain, if you need it.
The only requirement is that you build lldb with the matching version
of llvm.

regards,
pl
