[Gmsh] Runtime error

[Bracco Gianangelo]

Dear all
I downloaded a gmsh binary from your site and  I was testing your 
program with a simple geometry (copy of the geo file included).
To test the accuracy of the solution obtained by getDP for an 
electrostatic problem, I was decreasing the parameter lc to increase the 
density of nodes and I got the following message in a separate window 
("Microsoft Visual C++ Runtime Library").
Message:
"Runtime error!
Program: C:\gmsh-2.2.6-Windows\gmsh.exe
This application has requested the Runtime to terminate it in an unusual 
way. Please contact the application's support team for more information"

With lc=0.03 or greater no problem, instead with smaller lc values I got 
this error.
I checked the physical memory during the error and the program required 
slightly more than 1 GB while about 2GB were still available.
Many thanks for your effort in this project
Happy new year and
best regards
Nino
