[Bioc-devel] RMassBank build error

[Rainer Johannes]

an update:

I've switched back to the "default" initialize methods for Spectrum1 and Spectrum2 objects in MSnbase (not implemented in C) and with these installing RMassBank seems to work. 
I have however now to run some intense torture tests on MSnbase to ensure that we don't run again into the random memory problems that we had in MSnbase (issue https://github.com/lgatto/MSnbase/issues/138)
