Tells Boost.Regex to use a stack-recursive matching algorithm. This
|
||
is generally the fastest option (although there is very little in
|
||
it), but can cause stack overflow in extreme cases, on Win32 this
|
||
can be handled safely, but this is not the case on other platforms.

<p>
|

Tells Boost.Regex to use a non-stack recursive matching algorithm,

this can be slightly slower than the alternative, but is always safe
|
||
no matter how pathological the regular expression. This is the default
|
||
on non-Win32 platforms.
