Hello

the application closes with the following sentences (xcas 1.4.9-57 32 bits)

1: [] enter =(
2: assume(a,integer); 3*a=14; solve(3*a=14,a); enter =(
3: solve([x+y=3, x+y=5],[x,y]) enter =(

4: list2exp(list[ ], x) returns false // ok
5: exp2list(false) enter =( // => []
6: solve(1/x-(x-1)/x^2=1/(x^2),x) returns [x ]
6: exp2list(true ) enter [100.0,100.0,359.0,87,0,""] ? // => [ x ] (all values of x are solutions)

hp-prime
assume(a,integer); 3*a=14; solve(3*a=14,a); returns []
solve((3*a) = 14,a,'=') returns [] => false
solve((3*a) = 14,a,'x') returns 4.66666666667 ? // must generate an argument error
