I realize that. I just used "bash inside bash" example to show that the
problem is inside Cygwin/bash, not in cmd<->cygwin or
CreateProcess()<->cygwin interface.

I understand all this (I hope). And then I run

C:\>set CYGWIN=noglob
C:\>bash -c "c:\\cygwin\\bin\\ls.exe"
bash: c:\cygwin\bin\ls.exe: command not found

from cmd.exe, I expect that it should work (if not, could you finally
explain me there I am mistaken in this very case and rewrite it
properly). It does not. But in the same time any of the following works:

C:\>set CYGWIN=noglob
C:\>bash -c "c:/cygwin\\bin\\ls.exe"

C:\>set CYGWIN=noglob
C:\>bash -c "..\\bin\\ls.exe"  (c:\cygwin\bin is in the PATH)

That's why I think that the problem is that Cygwin (or bash) fails to
understand that "c:\\cygwin\\bin\\ls.exe" is the _absolute_ path, and tries
to locate ls using PATH directories. I see relatively long delay and HDD
LED blinking before "command not found" message appears (of course if
search directories are not in the file cache). Don't you think that all
this have nothing to do with globbing?

Hope to hear from you soon,
Dmitry
