I could not find the phrase in GRASS ML archives. Can you post a link?
Can you provide an example TIFF that crashes QGIS while building pyramids?

FWIW I would certainly vote for building external overviews instead of
internal. This would prevent eventual problems related to in-place
modification of TIFF file, improve data compatibility and prevent data
redundancy. External overviews in *.ovr files are no worse as to
performance or whatever, while they have advantages.
