Error occured in: Global
Message: memory allocation error: block too big
(tail call): ?
at this point, i am ready to conclude there is something going on in the Blizzard widget API, specifically Frame:GetRegions()
(or potentially farther down, inside of Microsoft's stuff).
it is always possible that Aloft is inducing this somehow, but...
i have seen this, and had users report this, in a number of addons over the past year or so (not only Aloft). Aloft probably encounters it the most because it cycles through a larger volume of frames than most other addons (as nameplates appear/disappear).
when it occurs in Aloft, it occurs in different locations (wherever frames are touched... which is all over the place; i have probably experienced it, and seen it reported, most often in the AloftManaBar module). the problem is completely intermittent, in code that otherwise executes continuously without problems. i myself have not seen it in months. i can't reproduce it. when i look at stack traces in Blizzard error dump files, the problem appears to originate several levels down in operating system DLLs related to memory management.
i readily confess to being stumped.
