Compiler segfaulting when compiling gmml

The "fix" is to just compile again. It never happens twice. Does seem to be related to compiling the Glycan/oligosaccharide class. Making note of it here. Not sure how frequent it is inside the dev env, happens relatively frequently (every other build sometimes, then nothing for a run of 20 or so builds) on my bare metal builds. Those numbers are extremely vague I wasn't tracking.
