Julia exits when hitting breakpoint

[s2maki]

When running Gallium in Windows with Julia 0.5.0, hitting a breakpoint causes Julia to exit (crash).

julia> using Gallium

julia> foo(x) = x+1
foo (generic function with 1 method)

julia> Gallium.breakpoint(foo)
Locations (+: active, -: inactive, *: source):
 * Any matching method added to #foo
 * Any matching specialization of foo(x) at REPL[2]:1


julia> foo(1)

$

Does this happen with all functions, or just small functions like this one?

[Keno]

Also versioninfo(), what version of windows, etc. since I can't reproduce this locally.

I can't reproduce this either on my windows machine.

I'm on Windows 7, pretty up-to-date with patches. Here's versioninfo:

julia> versioninfo()
Julia Version 0.5.0
Commit 3c9d753* (2016-09-19 18:14 UTC)
Platform Info:
  System: NT (x86_64-w64-mingw32)
  CPU: Intel(R) Core(TM) i7 CPU         870  @ 2.93GHz

  LAPACK: libopenblas64_
  LIBM: libopenlibm
  LLVM: libLLVM-3.7.1 (ORCJIT, nehalem)

It happens on larger functions as well. I was able to produce it on a 23 line function.

In some other cases, (setting it on a Base function like println, for instance) I get a crash.

Keith's original example works okay for me in Linux, Windows and macOS. Encountering a breakpoint set in println produces a segfault for me in Linux and macOS, and an infinite loop of 4 In coreio.jl:5 on Windows.
