Hello Phillipp,

Hope everything is fine with you!

I wanted to ask you if you had the time to look at my example file that recreates the problem in surface mesh using kernel exact exact .

thanks,

Jorge

Hello Philipp,

Thank you for taking time and looking at this.

I'm attaching a tar file with files for and example with the issue I was talking about.
One file is the main program, other file has the CGAL configuration (typedef ... etc), also
I'm sending two other files from CGAL I made little modifications.
In the file Complex_2_in_triangulation_3_file_writer.h I only added a conversion to double in order to
print.
In the file Surface_mesher.h, I found the loop where it hangs and I added a timer and a exit error that now is commented out, but at least you can see where is hanging.  Find those comments, modifications searching for JG.

As I said, with Exact_predicates_inexact_constructions_kernel works most of the time, but with Exact_predicates_exact_constructions_kernel it hangs with no error message.  I actually need the exact exact because previous to all of this I perform some intersections calculations with AABB.

Again, Thank you so much for looking at this!

Can you boil it down to a piece of code that compiles and shows the
issue when run? Otherwise it is really hard to diagnose your problem.

PS: Please don't remove the mail you are replying to. It makes it
incredibly hard to understand what you are talking about. Refer to esr's
awesome introduction to posting on mailing lists [1].
