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.
