This patch, r182112 on 4.6 branch, caused a test suite regression on arm-linux-gnueabi: +FAIL: gcc.c-torture/execute/20050713-1.c compilation, -O2 (internal compiler error) +UNRESOLVED: gcc.c-torture/execute/20050713-1.c execution, -O2 +FAIL: gcc.c-torture/execute/20050713-1.c compilation, -Os (internal compiler error) +UNRESOLVED: gcc.c-torture/execute/20050713-1.c execution, -Os because the compiler now ICEs: 20050713-1.c: In function 'bar3': 20050713-1.c:38:3: internal compiler error: in calculate_allocation, at vec.c:183 The same ICE also happens with today's trunk. /Mikael
