+Subject: [patch] workaround gcc46: prologue skip skips too far (PR 12435) #2
+
+Hi,
+
+this is an improved patch of a former:
+	[patch] workaround gcc46: prologue skip skips too far (PR 12435)
+	http://sourceware.org/ml/gdb-patches/2011-03/msg01108.html
+	cancel/FYI: Re: [patch] workaround gcc46: prologue skip skips too far (PR 12435)
+	http://sourceware.org/ml/gdb-patches/2011-03/msg01123.html
+
+For example `break error' does not work for debugging GDB with gcc-4.6.x.
+
+As gcc-4.6.0 and now even 4.6.1 still has this bug and I have seen a user(s?)
+on non-Fedora platform asking about this bug and as there may be enough
+binaries out there (although it affects only -O0 -g compilation) coded it
+properly I have coded the workaround properly this time.
+
+It does not solve overlays well, but the code just does not work for overlays,
+it has no other negative effect.
+
+I will update the code after FSF gcc gets fixed to minimize the workaround.
+
+No regressions on {x86_64,x86_64-m32,i686}-fedora16pre-linux-gnu.
+
+I would welcome a comment whether it is suitable for FSF GDB.
+
+
+Thanks,
+Jan
