-The GNU extension memmem() is known to be buggy on linux libc 5.0.9
-and before. Glibc upto 2.0.5 also has problems with memmem (), but
-these should not affect LilyPond.

-coredump from strstream::strstream () upon the first read of a file
+[LinuxPPC-R5, egcs-1.1.2-12c]
-[Linux Intel]
+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:

+[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.

+[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
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).
-I get bitten by this every once in a while, and I am very interested
-in hints what might be wrong. This problem has only been identified
-with libc-5.3 and libc-5.4 platforms, so you might try upgrading to
-6.0, ie. GNU libc-2.

-
-[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)
-
- yyFlexLexer::LexerInput (this=0x8294848, buf=0x82955f0 "", max_size=8192)
- yyFlexLexer::yy_get_next_buffer (this=0x8294848)
- My_lily_lexer::yylex (this=0x8294848)
-Fix: follow the install instructions of libg++: match the right
-library versions.
