Hi Ramana,
I can confirm that your reduced testcase triggers the ICE on the
cross-compiler that I use, although I need to add the following
command-line options:
-march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp
I guess you get these implicitly because of the different options
that you passed at configuration.
Thanks for looking at this.
Thierry
