Hi,
This release should fix the RC bug that has kept recent versions
of flex out of lenny. Please do delay for a few days, to see if this
version allows the packages on IA64 that were broken on the new kernel
versions there.
The changelog diff is below.

+flex (2.5.35-6) unstable; urgency=high
+
+ * [f0d7848]: Finish fixing the ia64 buffer issue. Previous commits
+ increased YY_READ_BUF_SIZE (where __ia64__ is defined) but left
+ YY_BUF_SIZE unchanged, so that didn't fix the problem in the end. In
+ the general case, the latter is twice the former. Therefore set it to
+ the same ratio in the ia64 case. Thanks to Cyril Brulebois
+ <k...@debian.org> for the heavy lifting.
+ Bug fix: "flex scanner push-back overflow", thanks to Sergei Golovan.

+flex (2.5.35-4) unstable; urgency=low
+
+ * [f6cc9ae] Narrow buffer size changes to just IA64
+ Increasing the buffer size on other architectures cause problems in
+ corner cases not caught by the test suite. So perhaps it is not better
+ to increase the buffer size unilatereally for all architectures, but
+ to just increase it for the architecture it is required on, namely,
+ IA64, and leave it unchanged on other architectures. This solution
+ should fix the new grave bugs, while not reopening the original but
+ that cause this change to be done in the first place.
+ Grave Bug fix: flex scanner push-back overflow, thanks to Sergei
+ Golovan (Closes: #505056, #504030)
+ * [debiandir:9a6d713] Fix VCS-Browser source field.
+ Bug fix: Useless VCS-Browser control field, thanks to Vincent Fourmond
+ (Closes: #503732)
+ * [d58780f] Wrap ECHO macro to avoid FORTIFY warnings
+ This change will enable flex scanners to be compiled with
+ -D_FORTIFY_SOURCE=2, which is a good thing security wise.
+ Bug Fix: flex causing warnings when compiled with FORTIFY_SOURCE,
+ thanks to Kees Cook. (Closes: #505233, #388438)

+flex (2.5.35-3) unstable; urgency=low
+
+ * Bug fix: "debian dir contains *.so", thanks to Raphael Hertzog
+ This is a simple rname of a file used purely in packaging, and has low
+ risk, but would allow compiling the flex source package with squeeze's
+ packaging tools. (Closes: #485095).
+ * [88bb2fc] Fix generation of broken output on ia64 when input is piped in
+
+ On ia64, flex appears to generate a completely different (and broken)
+ output depending on whether the input file is specified using shell
+ redirection or via a pipe.
+
+ This was traced back commit 3971e1a917548977cff71418a7c3575ffbc9571f,
+ by Alex Nixon <alex.ni...@citrix.com>: VFS: increase pseudo-filesystem
+ block size to PAGE_SIZE. PAGE_SIZE on ia64 kernels is larger than most
+ architectures - 16K is what most distributions (including Debian)
+ use. An effect of the above changeset, as verified by strace, is that
+ the read() and write() system calls issued by flex on a pipe will use
+ this bigger size. fread() appears to be properly hiding the actual
+ read size and is returning 8192 byte buffers to flex upon request. I
+ verified by this by instrumenting YY_INPUT to compare the fread data
+ with the original input file.
+
+ Its probably useful to note that the corruption happening here is that
+ the last 382 lines of the input file is being prefixed to the output
+ file. The only differences in the remainder of the file are the #line
+ numbers. I've also found that bumping YY_READ_BUF_SIZE up to 16384
+ seems to workaround the problem - but that may just be putting it back
+ into hiding.
+
+ The tradeoff here is between correct operation, by making flex's
+ buffer at least as big as the system buffer -- and not bigger, so that
+ we do not waste memory. At this point, fixing the isue seems more
+ important than worrying that flex consumes and additional 8KB of
+ memory.
+
+ This fix unblocks RC bugs on other packages.
+
+ Bug fix: "Generates broken output on ia64 when input is piped vs. shell
+ redirection", thanks to Chris Lamb. Fix based on comments by Dann
+ Frazier and Michael Casadevall. (Closes: #501960)
+ * [56ec97d] Fix doxygen comments to reflect actual argument name
+ Fix the comments to reflect the actual name of the function
+ arguments. This is a pure documentation fix.
+ Bug fix: "argument 'bytes' of command @param is not found in
+ the argument list of tp_scan_bytes(yyconst char *yybytes, int
+ _yybytes_len)", thanks to Ludovic Rousseau (Closes: #488272).
+ * [303084a] Merge branch 'topic--buffer-size-patch' [f6cc9ae] Narrow
+ buffer size changes to just IA64
