Bug when signing text?

[Stephane Corthesy]

Hi,

I'm using GPG on MacOS X Server; I downloaded from  
http://www.macsecurity.org/ a patch to make it compile on MOXS.

I encounter a strange behaviour with gpg, when signing some ASCII text:

Here the file to sign (the dashes are part of the file content):

--
signed
--

I issue the command:

gpg --armor --clearsign < /tmp/unsigned > /tmp/signed

and the returned file has modified the lines beginning with double  
dash (--). Now they begin with "- --". Is it normal?

hnw> gpg --armor --clearsign < /tmp/unsigned > /tmp/signed
gpg: can't mmap pool of 16384 bytes: Invalid argument - using malloc
gpg: Please note that you don't have secure memory on this system
