[Bug-gsl] bug with gsl_integration

[Johannes Hendriks]

Dear sir/madam

I have found a possible issue with the gsl_integration_qng
and gsl_integration_qag functions. Under particular conditions when these
functions fail to meet the specified relative or absolute tolerance,
instead of failing gracefully they are causing a seg fault.

I am running on osx 10.12.6 and compiling using the matlab mex compiling. I
have matlab 2017b, and am compiling with the command

mex intTwoK_mex.c -I/usr/local/include/ -lmwlapack -lmwblas -lgsl

I have attached a zip file containing a matlab script that will cause the
integration routine to fault.

Let me know if you require any further infomation.

Regards,
Johannes Hendriks
