Shader Hot-reloading Fails on Linux

[patternspandemic]

Environment

Archlinux Kodestudio 17.1 (linux64) with bundled Kha (ebff2335d0f58a5b01ac50cb66737f4694ec73f3)

Steps to Reproduce

• Using https://github.com/RafaelOliveira/ShaderEditor.git
• Set debug to Krom, and start
• Make change to ShaderEditor/Sources/Shaders/shader.frag.glsl and save
• Observe Debug Console output:

  Using Kha from .../resources/app/extensions/kha/Kha
  Creating Kha project.
  Compiling shader 1 of 1 (shader.frag.glsl).
  Compiling shader 1 of 8 (painter-colored.frag.glsl).
  Compiling shader 2 of 8 (painter-colored.vert.glsl).
  Compiling shader 3 of 8 (painter-image.frag.glsl).
  Compiling shader 4 of 8 (painter-image.vert.glsl).
  Compiling shader 5 of 8 (painter-text.frag.glsl).
  Compiling shader 6 of 8 (painter-text.vert.glsl).
  Compiling shader 7 of 8 (painter-video.frag.glsl).
  Compiling shader 8 of 8 (painter-video.vert.glsl).
  Done.
  Recompiling shader.frag
  Shader changed: shader_frag.
  Reloading shader shader_frag.

• Krom's build directory:
  • build
  • krom
    • krom.js
    • krom.js.temp.map
• Offending call: https://github.com/Kode/khamake/blob/master/out/HaxeCompiler.js#L101

Reproducing Outside Kodestudio

• cd into /path/to/kodestudio/resources/app/extensions/krom/Krom/linux/
• Run ./Krom /path/to/ShaderEditor/build/krom /path/to/ShaderEditor/build/krom-resources --watch
• Make change to ShaderEditor/Sources/Shaders/shader.frag.glsl and save
• From another shell, cd into ShaderEditor and rebuild: node /path/to/kodestudio/resources/app/extensions/kha/Kha/make.js -t krom
• Observe Krom segfault
• results of strace prob not helpful:

#### Also tested
- Hot reloading of project code seems to work OK. For example updating the body of a function called by render().
