Hi folks,

I have the problem regarding the compilation of the regular expression.

I have given the regular expression as follows:

" (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct
|Nov|Dec) ([ 0-9][0-9])
([0-9][0-9])(.*)"

and regcomp() function call gets aborted ( i think it is because of the
increased memory consumption at the time of regular expression
compilation ).
What is the reason behind this ?

Please put some light on the problem,

Thanks in advance,
torpedo

I don't observe undue memory consumption.  This regexp is one of the simplie
st.

Ooops ...

Sorry, the problems was lying somewhere else!
I was doing some illigal memory reference.

Thank you very much.
