When I compile app directly on ODROID I used:
arm-linux-gnueabihf
gcc version 4.8.4 (Ubuntu/Linaro 4.8.4-2ubuntu1~14.04.1) 

HVC instruction works form assembler, but when I call it from main, for
example: 
HYPERVISOR_console_io (HYPERCALL_WRITE, SYSTEM_UP_LEN, SYSTEM_UP_MSG);
then I get this in xl dmesg:
traps.c:2450:d2v0 HSR=0x90000046 pc=0x40008250 gva=0 gpa=0000000000000000

This doesn't happen with other compiler.

Ivan Pavic
