[Gmsh] [Fwd: GSL: function not continuous]

[P Hornby]

Hi,

Attached is a file that elicits

Error : GSL: function not continuous
(/home/burgers/pkg/cygwin/build/gsl-1.3/min/fsolver.c, line 40)
Fatal Error: Segmentation violation (invalid memory reference)

on element 40647. The GMSH version is 1.54.1 running on a Debian Linux
system. The windows version seems OK.

Also attached is a patch to gsl_brent.cpp that seems to fix the problem.
I don't know how robust this fix is as I've not tested it much. (How I
came to this solution is a story that does not bear repeating).

Cheers.
