Michael,

Simple Working Reference:
agent_id = session:playAndGetDigits(1, 6, 2, 10000,"#", "c:/DictationProject/audio/Validating.wav", "", "23");

Entering 45 returned nothing as expected, entering 23 returned 23 as expected.
-------------------------------------------------------------------------

Literal asterisk using parentheses:
agent_id = session:playAndGetDigits(1, 6, 2, 10000,"#", "c:/DictationProject/audio/Validating.wav", "", "(\*)");

Entering a single asterisk and waiting for timeout, and the timeout occurred as expected.
Error created:
2009-03-27 14:59:47 [ERR] switch_regex.c:184 switch_regex_match_partial() Regular Expression Error expression[(*)] error[nothing to repeat] location[1]

Entering a single asterisk and a terminating #, the asterisk created an immediate timeout as expected.

-------------------------------------------------------------------------

Literal asterisk without parentheses:
agent_id = session:playAndGetDigits(1, 3, 2, 10000,'#', 'c:/DictationProject/audio/Validating.wav', '', "\*");

Entering a single asterisk and waiting for timeout, and the timeout occurred as expected.
Error created:
2009-03-27 15:02:14 [ERR] switch_regex.c:184 switch_regex_match_partial() Regular Expression Error expression[*] error[nothing to repeat] location[0]

Entering a single asterisk and a terminating #, the asterisk created an immediate timeout as expected.
Error created:
2009-03-27 15:02:58 [ERR] switch_regex.c:184 switch_regex_match_partial() Regular Expression Error expression[*] error[nothing to repeat] location[0]
-------------------------------------------------------------------------

The error message correctly denoted the proper positions if the asterisk is being evaluated as a metacharacter, as well as looking for something to repeat.

for kicks try it with only one or the other, that is, with only
(\d{6}) or with only (\*) and see if you get that error. I'm curious
where it's bombing out. I think that test will help us figure out what
is going on.
