Dear Brian,
I found the error: I had not included two gsl source files into my
project: rowcol.c and view.c which contain functions called in
gsl_linalg_LU_invert. As a reminder, to make gsl work with Borland
Builder C++, it is necessary to include the source codes in the project.
The libraries (even the bcc ones) contain errors like bad entry points.
Thank you
Phil

Please send a small example which reproduces the bug, with details of
your operating system, compiler, etc.
