I included the .cc so it works with shared V8 builds (think Fedora, Debian, Ubuntu, etc.,or linking against a .so.)
I'll ifdef out smartos. That user base is a rounding error compared to the aforementioned distros.
LGTM if CI is green |

Looks like plinux doesn't like it.

LGTM, but yea, was just about to say what @Fishrock123 did. |

God, smartos is like a time machine back to the '90s. Okay, loosened the const-ness. CI: https://ci.nodejs.org/job/node-test-pull-request/2638/ |

Looks like something went wrong. Again: https://ci.nodejs.org/job/node-test-pull-request/2639/ |

Works on my machine. This might be a silly question, but does the CI actually exercise this at all? |
Not intentionally, I don't think. I thought about adding a test but it would be rather anti-social when core dumps are enabled. |

@cjihrig Thanks, added to the PR. Anyone wants to take one more quick look? |
I guess the test should be skipped on Windows? Other than that still LGTM. |

Eh, the RE should probably start with ^\s*

LGTM. Seems to be an issue with the CI though. |

Don't inline calls to node::DumpBacktrace() and fflush(), it makes the generated code bigger. A secondary benefit of moving it to a function is that it gives you something to put a breakpoint on.

@bnoordhuis should this be backported? |
Ideally, yes. |
due to the AIX + compiler failures I'm going to hold off on this change for the v4.5.0 release @bnoordhuis would you be willing to backport this PR along with #7508, #7544, and any other potential commits that need to land with this? |
ping @bnoordhuis sorry about the other message. Would you be willing to backport a working version of this as mentioned above |
