gdb redirection arguments are passed as arguments to debugged executable under Cygwin

[Dave Curtis]

Hi.

I just installed Cygwin and ddd v 3.3.

I am trying to debug an executable called hapclust.exe. The arguments should be
hphc0104.par hcsnp04.dat hphc0104.out. I press F2 and enter these as arguments.
They are displayed as Arguments in the Run Program window as:

hphc0104.par hcsnp04.dat hphc0104.out

If I run the program with a breakpoint near the start it shows:

(gdb) run hphc0104.par hcsnp04.dat hphc0104.out

But, it says argc=0. And nothing appears in the Exectuion Window as it should.

If I print the contents of argv[] I get the following:

argv[0]="/home/dcurtis/hapclust/hapclust"
argv[1]="<"
argv[2]="/dev/tty2"
argv[3]=">"
argv[4]="/dev/tty2"
argv[5]="2>&1"
argv[6]="hphc0104.par" etc

So the arguments which should go to gdb to redirect output are going to my
executable instead.

I can't understand why this is happening to me and why nobody else has reported
it.

Please let me know where to go from here.

Regards

 - Dave Curtis
