<!-- DIV {margin:0px;}-->Hello,
Sorry, I reactivate this thread
(http://cygwin.com/ml/cygwin/2007-03/msg00029.html) but I have exactly the same
error with process make.
bash: cannot duplicate fd 31 to fd 0: Bad file descriptor
I ran my process make under strace (strace -ostrace.out bash -c make) and got
this (have a look at the two last lines)
Does anyone have an idea ?
Thanks,
aoyou

Maybe this will lead to a
