I just tried to compile the Suse Linux package
MyODBC-unixODBC-3.51.26r1127-1.62
with the GNU C compiler version 4.4 snapshot 20081128.
The compiler said
gcc -DHAVE_CONFIG_H -I. -DNONTHREADSAFE -I/usr/include -O3 -DDBUG_OFF
-I/usr/include/mysql -fmessage-length=0 -D_FORTIFY_SOURCE=2 -fstack-protector

libmyodbc3_la-error.lo -MD -MP -MF .deps/libmyodbc3_la-error.Tpo -c error.c

------- Comment #4 from jakub at gcc dot gnu dot org 2008-12-01 17:35 -------
The bug is in expand_builtin_stpcpy, where it doesn't handle COMPOUND_EXPRs
resulting from build_call_expr as other routines do.
