Ada GPS editor crashes when pasting in text

Question

While editing this package body:

package body ai is

   type Possible_Boards is

end ai;

GPS crashes when pasting the following code after the is:

    let bestMoves = [
        0x1160:1,
        0x1205:0,
        0x1304:0,
        0x1340:0,
        0x1403:0,
        0x1430:0,
        0x1502:0,
        0x1520:0,
        0x1601:0,
        0x1610:1,
        0x1700:0,
        0x2222:0,
        0x2330:0,
        0x2420:0,
        0x2510:0,
        0x3140:1,
        0x3203:0,
        0x3230:0,
        0x3320:0,
        0x4103:0,
        0x4130:1,
        0x4220:0,
        0x5120:1,
        0x6101:0,
        0x6110:1 ];

Obviously, this isn't Ada code, but crashing GPS doesn't seem reasonable.
