"Segmentation fault: 11" on OSX 10.11.6 and XCode 8
node-scrypt 6.0.3 has been working fine for me until recently when I rebuilt my node_modules folder. I am now getting Segmentation fault errors when making scrypt calls.
The only change I can think of is that I installed Xcode 8 and am now seeing clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 message when installing.
I can replicate the problem when running the tests in the scrypt folder. The test crashes when making the var params = scrypt.paramsSync(1); call. Here is the output:

This might help you. I tried reinstalling and running the scrypt tests under node v6.8.0 (I was previously using v4.6.0) It crashes at the same place but the error message is a bit more informative:
dyld: lazy symbol binding failed: Symbol not found: _clock_getres
Referenced from: /Users/me/test/node_modules/scrypt/build/Release/scrypt.node
Expected in: /usr/lib/libSystem.B.dylib

Referenced from: /Users/me/test/node_modules/scrypt/build/Release/scrypt.node
Expected in: /usr/lib/libSystem.B.dylib
Trace/BPT trap: 5
I'm also getting similar behaviour so would love to get some workarounds on this please
While I do see the warning when using v6, compilation proceeds without error. Modules inherit this from node. AFAIK, as of v7 node links to libc++ instead of libstdc++. I suspect you'll see the same warning with other projects that use node-gyp (redis?) until you start using node v7 or Xcode 7. I don't see the warning when using node v7.
➜ *** git:(master) ✗ nvm use v6
Now using node v6.9.1 (npm v3.10.8)
➜ *** git:(master) ✗ cd node_modules/scrypt

I spent quite a lot of time looking into this 3 weeks back, and it looks like this is an issue affecting many modules where XCode 8 is running on El Capitan. The only fixes I found were to (a) downgrade Xcode 8 to Xcode 7, or (b) to upgrade to MacOS Sierra. I updated to Sierra and scrypt works fine now (tested under node 4.6.1 and 6.9.1).
