Boost::regex throws invalid execption when assigning match text

[Raymond Chandler III <raymond.chandler.ctr@…>]

Boost::regex::assign throws an exception on "[A-Za-z_:,=\t\{\[\]\}]" when it should not. The offending text within the text(heh) is "[SomeMatchText\{\[\]\}]SomeMatchText]". It does not matter where in the text "\{\[\]\}" is located it will always throw an exception if provided in that order.

However, if you do "[\}SomeMatchText\{\[\]]" it will not throw an exception. I haven't tried other split combinations.

This bug was noticed in version 1.38, the changelogs do not seem to indicate this bug being fixed.

Works for me, note that the escapes need to be doubled up if the string is embedded in the source file. For example:

boost::regex e("[A-Za-z_:,=\\t\\{\\[\\]
}]");

Remember that the compiler gobbles up the first escape.

Please reopen if you have a test case.
