latest gdb snapshot issues with ecos binaries

[Michael Malone]

Hi All,

I am running Ubuntu 8.10 and I built a program for (Jan 11 CVS snapshot 
of) eCos targeted at an i686, using gcc-4.2.3 but when I tried to run 
the produced binary I got this error message:

This is using yesterday's snapshot (Jan 22) of GDB from CVS.  I got the 
same thing when I used the version of gdb that came with gcc-4.2.3
Does anyone know what's going wrong or of a workaround?

Thanks,
Michael

Are you sure you're using a snapshot?  It should have a version like
6.8.50.0.<date>.

I got the same symptom whether I used the ubuntu packaged version or the 
snapshot.  For the example I got lazy and just used the version on my 
$PATH.  Though if there's a library somewhere that might make a 
difference, let me know and I'll remove the older version.  For now, 
here's the same out from the snapshot version.

Thanks,
Michael
