Wu, If you have a second, could you take a look at the behavior of the region r5 in the model share/db/m35.g when doing boolean evaluation with the brep command? It's giving out a series of errors and then crashing. I think part of the problem is if you make a comb of the first two items in r5 (i.e. comb test.c u s5 - s6) and then convert test.c to a brep, it's giving out a warning and generating what appears to be a non-solid brep. Comparing that brep to the raytraced csg comb, it looks like it's running into an issue with trimming overlapping coplanar faces. Judging by the other warnings that follow before the crash, I'm guessing it's accumulating non-solid geometry until something really unexpected happens and it segfaults.
