On Linux/x86-64, revision 163191 gave

FAIL: gfortran.dg/array_memcpy_3.f90  -O  scan-tree-dump-times original
"memcpy|(ref-all.*ref-all)" 2
FAIL: gfortran.dg/array_memcpy_3.f90  -O  scan-tree-dump-times original
"memcpy|(ref-all.*ref-all)" 2

Revision 163187 is OK. This may be caused by revision 163189:

http://gcc.gnu.org/ml/gcc-cvs/2010-08/msg00400.html

Linux/ia32 doesn't have this regression.

The pattern doesn't match even though I see two memcpy calls!?

I am using

# make RUNTESTFLAGS="--target_board 'unix{-m32,}'" check

2 failures are 1 for 64bit and 1 for 32bit.

I see the fails, but the pattern should still match.

I was wrong. Linux/ia32 has the same regression:

FAIL: gfortran.dg/array_memcpy_3.f90  -O  scan-tree-dump-times original
"memcpy|(ref-all.*ref-all)" 2

Does "memcpy|(ref-all.*ref-all)"  need to be "(memcpy|(ref-all.*ref-all))" or
perhaps "(memcpy|ref-all.*ref-all)".  Everyplace else I see a | in a scan
statement there are parentheses around the options.

! { dg-final { scan-tree-dump-times "memcpy|ref-all.*ref-all" 2 "original" } }

worked for me on IA64 where we have 2 memcpys' in the output.  Neither of my
suggestions from comment #7 worked.  I don't know if this will work on a
platform
which generates the 'ref-all' strings instead of memcpy's.  All my platforms;
IA64, PA, x86 seem to generate memcpy.
