Mshmet segmentation fault error

User Help
#1

Hi,

When running mshmet I get a Segmentation fault following the Phase 1. I have compiled the olderVersionThatWorks and I am testing with the 3D example found in this post. The files are temp.mesh and temp.sol. Below is the complete output.

Any idea what could be wrong?

Thanks!

Hi, I have the same problem. Did you solve?

Hi,

I think I have actually just found it. In file hash.c, subtract 1 to inival, so in the end replace lines 27 and 145 by inival = 2147483647;

Let me know if this works for you.

It may seem strange but I solved it by adding to lines 71 and 72 (in the for loop after /* set adjacency */), the lines:

 char str[] = "";
 fprintf(stdout, str);

I’ve only tried it for the 3D case and it seems to work fine.

Anyway, your solution might make more sense and I’ll try it in the next few days.
