Memory

[Zepeng-Mu]

Hi,

I encountered a memory error while subsetting two GRanges by overlapping:

Error in .Call2("C_find_overlaps_in_groups_NCList", start(q), end(q),  : 
  build_NCList: memory allocation failed

10. | .Call2("C_find_overlaps_in_groups_NCList", start(q), end(q), q_space, q_groups, start(s), end(s), s_space, s_groups, nclists, nclist_is_q, maxgap, minoverlap, type, select, circle.length, PACKAGE = "IRanges")
-- | --

The two GRanges are each about 50,000 features longs and < 10MB. I suspect the true cause is not memory but I have not been able to trouble shoot it.

Thanks so much!
