Version: 4.7.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: dcb314@hotmail.com
I just tried to compile the file
gcc/testsuite/gcc.target/arm/pr50305.c under valgrind on trunk
dated 20120219 on an AMD x86_64 box.
Valgrind said
==4007== Invalid read of size 8
==4007== at 0x6B0212: adjust_address_1(rtx_def*, machine_mode, long, int,
int) (emit-rtl.c:2043)
