bug#18126: 24.4.50; Arithmetic range error while attempting to drag vertical scroll bar

[Dmitry Antipov]

Using Lucid build, an attempt to drag slider of a vertical scroll bar
with mouse causes an arithmetic error:

Arithmetic range error: "truncate", 1.0e+INF

Corresponding buffer should have enough (a few thousands) lines.

The backtrace is:

Breakpoint 4, rounding_driver (arg=..., divisor=..., double_round=0x6197d1 <double_identity>, int_round2=0x6196c2 <truncate2>,
     name=0x71f78b "truncate") at ../../trunk/src/floatfns.c:372
