+Compiling with -O2 -finline-functions will cause crashes during
+parsing stage.

+[All platforms] 
+
+When dealing with beaming that is not correct (eg quarter notes in
+beams.), you can get the following assert.  This is a serious bug, but
+a good solution is quite a lot of work.

+
+LilyPond occasionally crashes while parsing the initialisation files.
+This is a very obscure bug, and usually entering the commandline
+differently "fixes" it.

+
+       lilypond -I. ./input.ly

+
+This behaviour has been observed with machines that have old libg++
+versions (LinuxPPC feb '98, RedHat 4.x).  
+
+
+
+[Linux Intel]
+
+A problem resembling the previous: usage of libg++.2.8.x with the
+wrong version of libc results in a coredump from the scanner while
+reading the init files.  Stacktrace:
+
+       ios::eof (this=0x0)
