[Bug c++/22595] New: [4.0 regression] wrong warning: control may reach end of non-void function

["debian-gcc at lists dot debian dot org" <gcc-bugzilla at gcc dot gnu dot org>]

[forwarded from http://bugs.debian.org/319309]

regression from 3.4, fixed in 4.1

Compile the attached example source code with:

	g++ -Wall -O3 -c bug.cc

g++ produces the warning:

bug.cc:9: warning: control may reach end of non-void function 'char* f(char*)'
being inlined

This is wrong, as should be obvious, since every possible control path
in f() either leads to a return or a throw.  g++ 3.x correctly
analyses the code and does not generate a warning.
