[help]: Print statement and SIGBUS error?

[Li_Dong]

Dear all,

I am writing an implementation of Delaunay triangulation and Voronoi diagram. And I am facing a strange error, that is if I add a print statement before some subroutine (line 522 in DelaunayAndVoronoi.F90), there is no error, but if not, SIGBUS or segmentation error will occur.

My code can be obtained through

git clone git://github.com/dongli/DelaunayAndVoronoi.git

then go into "UnitTest" dir and type "make".

PS: If youdon't have installed NetCDF library, you can comment out "use NFWrap" and "DelaunayAndVoronoi_Output" subroutine in DelaunayAndVoronoi.F90, and also the object dependency in Makefile.

Thanks for any help!

Cheers,

DONG Li

I have found the bug, which hides very deeply.

When I use recursive subroutine, I declare two version of a variable "found" and "realFound", which should be merged. The judging condition for using which one is buggy. Now the bug has gone. : ) If you are interested, you can check out my code managered by git.

Cheers,
