I wonder if list members might throw any light on the term alpamṛtyu
    occurring in a 17th-century Sanskrit text (Yādava's Tājikayogasudhānidhi).
    I would have supposed it to be a scribal error for apamṛtyu (in the
    sense of 'untimely death') were it not that the metre requires that
    the first syllable be long. I do not recall seeing the word in other
    Sanskrit texts, but a quick web search returns quite a number of
    hits in the vernaculars, including some from the Rāmcaritmānas.
    However, I am not sure from these whether to understand alpamṛtyu as
    untimely death (= akālamṛtyu), as a nearly but not quite fatal
    accident, either, or as something else entirely.
