It also works,

Putting the send_user above inside
test.exp also gives a pattern matching...
I am lost.

Using gdb_test_multiple, I can see that the 
start and end added to the pattern of gdb_test 
is not the cause of the problem:

gdb_test_multiple  "print 1122233\n"  \
        "Check int constant with gdb_test_multiple"  \
        {  \
        -re ".*1*2*.*"  {  \
          pass "pattern found"  \
          } \
        -re ".*"  {  \
          fail "pattern not found"  \
          } \
        }

gdb_test_multiple  "print 1122233\n"  \
        "Check int constant with curly braces using gdb_test_multiple"  \
        {  \
        -re ".*1{1,}2{1,}.*"  {  \
          pass "pattern found"  \
          } \
        -re ".*"  {  \
          fail "pattern not found"  \
          } \
        }

Gives a PASS for the first and a FAIL for the second.
