+[LinuxPPC-R5, egcs-1.1.2-12c]
+
+Serious egcs-1.1.2-12c (stock LinuxPPC R5) bug on ppc:
+
+       *dest++ = *src++;
+
+Bug report filed, fixed in egcs-1.1.2-12f or gcc-2.95-0a.
+Although we've currently got a workaround in place, the compiler
+is buggy; you should upgrade:
+
+       ftp://dev.linuxppc.org/users/fsirl/R5/RPMS/ppc/ 
+
+
+[LinuxPPC-R4, egcs-1.0.2]
+
+All compiling with -O2 is suspect, in particular guile-1.3, and
+Lily herself will break.
+
+
+[Linux i386]
+
+A binary RPM of Guile 1.3 has been distributed from the LilyPond ftp
+site.  This binary was made in RedHat 5.x, and it will fail if this
+RPM is used with RedHat 6.x.
+
+[GUILE 1.3.2]
+
+Guile 1.3.2 is buggy in several respects. Do not use it for LilyPond.
+
+[LinuxPPC, egcs-1.1b]
+
+Lilypond 1.1.35-1.1.51,...:  Wierd errors in guile scm_gc_mark ()
+
+
+[All platforms] 
+
+Some bugs may be captured in input/bugs/*y
+
+[Linux i386, RedHat 5.2 with updates to 6.0]
+
+Compiling with 
+
+       configure --disable-checking --enable-printing --disable-optimise --disable-debugging
+
+results in core dumps, during parsing of init files. Cause unknown.
+Solution: use
+
+       --enable-checking and --enable-optimize
+
+[Linux libg++ 2.7]
+
+LilyPond occasionally crashes while parsing the initialisation files.
+This is a very obscure bug, and usually entering the commandline
+differently "fixes" it.
+
+       lilypond input.ly 
+
+and
+
+       lilypond -I. ./input.ly 
+
+makes a difference
+
+Typical stacktrace:
+
+       SIGSEGV
+       __libc_malloc (bytes=16384)
+       ?? ()
+       yyFlexLexer::yy_create_buffer ()
+       Includable_lexer::new_input (this=0x8209a00, s={strh_ = {
+               :
+
+This behaviour has been observed with machines that have old libg++
+versions (LinuxPPC feb '98, RedHat 4.x).
