And getting 50M, if your dmesg was right... 8-) 8-).

My guesses, in order, would be (1) an unitialized variable,
or (2) it loads sparsely, or (3) it has a really bogus table
entry that claims it needs that much memory.  It doesn't look
magic enough to be a sign extension/signed-unsigned pun error.

Other than starting at the code that's supposed to load the
table in, and printf'ing until you find out why it's thinks
50M is a nuce number, I don't know what to tell you...
