Hi, GPCLIB will on rare occasions segfault on me. For example, attempting to union the two attached polygons will always segfault. This is on OS X. Does anyone else have this problem or know how to fix it? -Scott Poly 1: [[1]]$x [1] 1.99917662 1.96950743 1.91320263 1.89742912 7.25288526 8.24146922 [7] 1.64772929 0.91502421 -1.03937798 0.06113105 -0.89445414 -3.59680448 [13] -3.61199049 1.54124461 [[1]]$y [1] 7.4222754 5.3315017 1.8361718 1.8465662 -1.6825414 -2.4381155 -5.8159161 [8] -5.3739624 -0.8106083 1.5137002 1.8257775 4.3562953 5.2871664 7.5700518 [[1]]$hole [1] FALSE Poly2: [[1]] [[1]]$x 8 5 97 89 96 73 84 1.6477293 0.9150242 -1.0393780 0.5971623 1.3536103 7.2528853 8.2414692 [[1]]$y 8 5 97 89 96 73 84 -5.8159161 -5.3739624 -0.8106083 1.6578244 2.2049287 -1.6825414 -2.4381155 [[1]]$hole [1] FALSE -------------- next part -------------- A non-text attachment was scrubbed...
