RE: [ECOS] ConfigTool crashes on latest Cygwin

[Moseley, Drew]

I have seen a similar crash of command line ecosconfig with the latest
cygwin1.dll.  It is getting a divide-by-zero error.  The CDL causing the
failure is in
packages/hal/arm/xscale/verde/current/cdl/hal_arm_xscale_verde.cdl;
specifically the definition of CYGNUM_HAL_RTC_PERIOD as "calculated
1000000/CYGNUM_HAL_RTC_DENOMINATOR".  If I replace
CYGNUM_HAL_RTC_DENOMINATOR with its default value then everything works.
I have put some debug code into ecosconfig to confirm that it is a
divide-by-zero failure however I have not tracked down where the zero is
coming from.  I will continue my debug but hopefully someone with more
knowledge of the inner workings can provide some insight.

Subject: [ECOS] ConfigTool crashes on latest Cygwin

I've recently re-compiled ConfigTool using a receipe that has worked in
the 
past and now find that when I run it on the latest version of Cygwin 
(cygwin1.dll 1.5.19-cr-0x5ef)  it appears to crash just after opening
the 
repository. I've tracked it down as far as the call to

                        NewCdlConfig->set_hardware (DefaultHWName, 
&CdlParseErrorHandler, &CdlParseWarningHandler);

which is line 962 in configtooldoc.cpp in my sources which are a week
old 
CVS snapshot.

At this point it all disappears into libcdl and the trail goes cold as
far 
as my ability to track it goes.

Interestingly, if I move the executable onto another system with an
older 
version of cygwin (cygwin1.dll 1.5.12) then it runs quite happily.

Has anyone else encountered this or better still found a fix.

Thanks,

    Andy..
