Subject: Add some debugging features if DEBUG defined
X-Git-Tag: v0.9.8~167
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=99bec95482db5a395f450c972e5d947af42a01fd;p=thirdparty%2FPython%2Fcpython.git

Add some debugging features if DEBUG defined
(fetch the filename as a string so I can see it with dbx, and set f_lineno);
call abort() when detecting an "undetected" error.
