Description:
Windowing back with a count greater than 1 fails.
Repeat-By:
Preceding a CTRL-b by a count greater than 1 (e.g. 3CTRL-b) either
results in the cursor addressing the wrong line, or a core dump.
Occurs with version 7.3 of ex_vmain.c on our 4.2 system.
Fix:
The fix to this problem is trivial. Edit ex_vmain.c and make the
following change:
ex_vmain.c.old:
case CTRL(b):
vsave();
if (one + vcline != dot && vcnt > 2) {
-> addr = dot - vcline + 2 + (cnt-1)*basWLINES;
forbid (addr <= zero);
dot = addr;
vcnt = vcline = 0;
}
============================================================================
ex_vmain.c.new:
case CTRL(b):
vsave();
if (one + vcline != dot && vcnt > 2) {
-> addr = dot - vcline + 2 - (cnt-1)*basWLINES;
forbid (addr <= zero);
dot = addr;
vcnt = vcline = 0;
}
