Compiler Problems?

[Thomas D. Dean]

> How does it fail?  Use gdb.  What compiler options?

When I speak of the scilab port, I mean scilab and the depends, lapack
and blas.  There are two cases.  1.  the port as cvsup'd.  2.  the
port modified to use cc and f77 of 6.2-stable.

In the fail mode, scilab does not return to gdb.  I used the default
scilab/lapack/blas compiler options.  The only change I made was to
switch compilers.

Case 1:
On -stable, 'scilab -debug', built with with the port as cvsup'd,
hangs using 90% of one cpu.  'scilab -debug' starts scilab in gdb. The
scilab display is frozen.  If I drag a window across the scilab
window, it does not refresh.  I let it run for 10 minutes.  It never
returns to the gdb prompt.  On the console, I saw

# scilab (menubar -> demos -> signal processing -> bode plots)

Case 2:
On -stable, scilab, built with cc 3.4.6 and f77 3.4.6, the same
sequence of actions produces the bad window messages, but, does not
hang.  Scilab produces the plots, responds to prompts, etc.
