Quotes after --args

Quotes after --args

["Markus Bühren"]

Hi,

I am using the GNU gdb 6.8 under Windows. I am trying to run a program that is invoked like 

  test.exe -f "my testfile.txt"

in batch mode. This is my command line:

  gdb --eval-command=run --batch --args test.exe -f "my testfile.txt"

My program should get two arguments, '-f' and 'my testfile.txt'. However, replacing my actual program test.exe by a program that just prints the input arguments, I get the following result:

  C:\>gdb --eval-command=run --batch --args test.exe -f "my testfile.txt"
  [New thread 6180.0xad0]
  argv[0] = >>C:/test.exe<<
  argv[1] = >>-f<<
  argv[2] = >>my\<<
  argv[3] = >>testfile.txt<<
  
  Program exited normally.

Can you help me to avoid that the file name is splitted into two arguments, with replacing the blank ' ' after 'my' by a backslash '\'? I have tried a lot of combinations of double double quotes '""', escaped double quotes '\"' and so on but I did not manage to get the file name passed as a single argument into my program.

Yours
Markus

PS: Renaming the file is not an option - actually, I already simplified matters here to a file name with a blank in it.

PPS: For your reference, this is the C code of my simple program returning the arguments:

#include <stdio.h>

void main(int argc, char *argv[])
{
  int k;
  for(k = 0; k < argc; k++)
  {
    printf("argv[%d] = >>%s<<\n", k, argv[k]);
  }
}

It's a bug.  GDB handles the whitespace in a way that works on Posix
platforms, but not on Windows.

You can always use its 8+3 alias, something like mytest~1.txt (use the
"dir /x" command from the shell prompt to see the actual name),
instead of the long name.  This is a workaround, though.
