Snippet available on request, but to put it in understandable terms... So far I have encountered that this is what makes the game crash, regardless of having other mods in the pack or not:

Crafting CoFH conversion blocks (either in or out, doesn't matter it crashes regardless)
Placing CoFH conversion blocks (second verse is the same as the first)
Installing data terminal
Attempting to open ANY interface of the blocks or items within the AcademyCraft mod

Are you sure your forge version is 10.13.4.1517 or higher and you GLSL version is 3.0 or higher?
So far I only have these guess.

I run 10.13.4.1614 for forge, so that definitely isn't the issue. GLSL on my rig is set to automatically update to the latest stable release.

outdate issue.
