Segfault with sql_execute_df about heavydb

[asuhan]

Thank you for the report! Which operating system / tool-chain versions are you using? Also, do you have libunwind installed?

@m1mc We'll have to look into it.

[TomAugspurger]

I'm on macOS 10.12.5. Not sure what all versions would be in the tool-chain, but clang --version outputs

Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin16.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Anything else that would be useful?

I don't think I have libunwind installed.

What CMake options you using? Specifically, are you building with CUDA enabled or disabled?

[m1mc]

second Andrew.
@TomAugspurger I did repro a segfault w/ HAVE_CUDA off, otherwise pymapd was working well w/ latest sql_execute_df on my macOS 10.11. The root cause of my segfault is due to access to void cuda manager by non-CUDA build or CUDA build in CPU mode.

[TomAugspurger]

Thanks for the info, this build was with CUDA disabled. I'll give it a shot with it enabled.

2966fac should fix it, let us know.

[TomAugspurger]

@asuhan thanks, that fixed it.
