[Bug c/30502] compiler inlines slightly invalid function without warning

["yakov at emc dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #2 from yakov at emc dot com  2007-01-18 19:18 -------
Subject: Re:  compiler inlines slightly invalid function without
 warning

 gcc -O2 -Wall -c -fno-inline rtv.c
rtv.c: In function `compute_tables_error_code':
rtv.c:18: warning: control reaches end of non-void function

gcc -O2 -Wall -c rtv.c  <-- no warning here

With '-fno-inline' compiler generates very useful warning - the return 
stmt has been missing.

This is my point.

sincerely,
yakov
