Compile error

Cant compile on SuSE Enterprise Server 10

Compilation error:

Minor Compile Problem.

Compiling libstrfunc out of the box, with gcc 3.0
reveals the following compile time problems:

cfglex.c: 120 switch statement may not contain a
pointer
split.c: 244 switch statement may not contain a pointer

changing these case to read (char)NULL rather than
simply NULL corrects this error.

Knowing the GNU libc, I would bet you free() something
that you did not malloced. After all, an adress of 0x18
is a bit strange.
