[bug-gawk] Win32 Gawk 4.0.0 bugs

[Giorgio Palandri]

Hi; maybe I've found two bugs in gawk 4.0.0 for Windows. The first one
is in sprintf function (see following text):




THE SOURCE PROGRAM
------------------------------------------------------

C:\tmp>type test.awk

BEGIN {
        c = 100
        z = sprintf("%05s", c)
        print z
}


GENERIC AWK INTERPRETER (maybe MAWK, I'n unsure)
------------------------------------------------------

C:\tmp>awk -f test.awk
00100


OK!


GAWK 3.1.6
------------------------------------------------------

OK!


GAWK 4.0.0 (same problem in dgawk)

C:\tmp>gawk -f test.awk
  100

As you can see, no padding with zeroes.


The second bug is in DGAWK: if I set a breakpoint OUTSIDE of a switch
statement, all works fine.
If I set a breakpoint INSIDE a switch statement the breakpoint is set
on a following line (the increment seems arbitrary).


Bye,
