Hi Natalia,<br>
<br>
my first guess would be that you have very large coefficients in
your constraints (i.e., larger than 1e+20). At least, the assert
comes up since a coefficient with absolute value > 1e+20 is added
to an LP row.<br>
<br>
If not, could you run again with gdb and check where the large value
comes from, and perhaps send the backtrace?<br>
<br>
Best,<br>
