Subject: [Bug c/31924]  New: gcc accepts invalid suffixes for decimal float constants
Date: Mon, 14 May 2007 20:50:00 -0000	[thread overview]
Message-ID: <bug-31924-4503@http.gcc.gnu.org/bugzilla/> (raw)

The change to the C preprocessor to recognize "df", "dd", and "dl" as suffixes
for decimal floating point constants also allows "fd" and "ld"; a check for
that assumed that the the letters are examined from left to right, but they are
examined from right to left.  There are no errors for the following:

  double a = 1.ld;
  double b = 1.fd;

I'm testing a fix, but wanted a PR to reference for a patch to the 4.2 branch.
