Comment(by GeorgSWeber):
Michael,
I *am* willing to hunt this bug down to its end, and by now, I know how I
could e.g. replace the old dlmalloc v2.6.5 in omalloc "seamlessly" by any
of the newer versions, or even by a version especially adapted (to use
both sbrk()/mmap() or only one of these on certaim platforms, or
whatever).
But I am bit at a loss by what you mean by "switching back to mmap makes
the appeared minpoly issue go away".
1. Under which circumstances does this "minpoly issue" occur? Please give
me a kind of recipe.
2. Under which circumstances, in contrast, does the "minpoly issue" go
away? Again, please give me a list of what to be done/seen.
Hopefully this (steps 1 and 2) could be done on a Mac OS X 10.4.11 box
(either Intel or PPC), or else I will have to work remotely.
Thank you!
Cheers, gsw
