--- Comment #11 from christophe.lyon at st dot com ---
I've noticed that pr61160-2.C crashes at execution (under qemu) when:
* GCC configured as:
--target=arm-none-linux-gnueabi
--with-cpu=cortex-a9
--with-fpu=neon
* pr61160-2.C compiled with:
-O3 --param ipa-cp-eval-threshold=1 -lm -march=armv5t -mthumb
Removing -mthumb makes the execution succeed.
