Description Magnus Fromreide 2005-04-29 21:12:45 UTC 
When compiling I get the annoying warning below.
I did not get it with g++-3.4. g++-4.0 do produce it.

$ g++ --version
g++ (GCC) 4.1.0 20050429 (experimental)

$ g++ -Wall -O1 -c foo.C -o oasAux.o
foo.C: In function 'void f()':
foo.C:15: warning: control may reach end of non-void function 'void* f2(unsigned
int)' being inlined

Example program demonstrating the problem

Compile with g++ -Wall -O1 -c foo.C to see the error

Even the code given in the bug has no dead code the bug is in the same in that GCC creates dead code.
