Good, but can we fix the test. I have found the tests are very good
indicator into the health of my cygwin1.dll build

The window freezes and I have to use task manager to kill it.
I will try to gdb the exe left in the testsuite....

sed and sh give stackdump with no info (well, nothing I can see)

For example :

Exception: STATUS_ACCESS_VIOLATION at eip=00000000
eax=00000000 ebx=00000007 ecx=61084EEC edx=00000000 esi=6108D15C
edi=6108D164
ebp=0241F9F8 esp=0241FE94 program=f:\Cygwin\bin\sed.exe
cs=001B ds=0023 es=0023 fs=003B gs=0000 ss=0023
Stack trace:
Frame     Function  Args
End of stack trace
