[geos-devel] [GEOS] #343: After applying a buffer over a multiline the library starts growing in memory usage and hungs

[Martin Davis]

Yikes!  That's one nasty dataset.  JTS has issues with it as well - I 
wasn't able to get the buffer to complete.

As a workaround, you could buffer each line separately and then 
UnaryUnion the results.
