Summary: Wrong return statement warning with -Wreturn-type in
template class method
Product: gcc
Version: 3.4
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: nicolas dot burrus at lrde dot epita dot fr
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: i686-pc-linux-gnu
GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu
gcc 3.4 emits a wrong warning for methods in template class without
return call, even if the end of the method will never be reached.
Environment:
System: Linux ouagadougou 2.4.21 #1 Fri Jul 25 11:19:01 CEST 2003 i686 GNU/Linux
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../../lrde/ext/gcc/configure --prefix=/home/lrde/lrde/usr/gcc-3.4 --enable-languages=c,c++ : (reconfigured) : (reconfigured) ../../lrde/ext/gcc/configure --enable-languages=c,c++ --prefix=/home/lrde/lrde/usr/gcc-3.4 : (reconfigured) ../../lrde/ext/gcc/configure --enable-languages=c,c++ --prefix=/home/lrde/lrde/usr/gcc-3.4 : (reconfigured) : (reconfigured) /home/lrde/stud/burrus_n/work/lrde/ext/gcc/configure --prefix=~lrde/usr/gcc-3.4 --enable-languages=c,c++ : (reconfigured) /home/lrde/stud/burrus_n/work/lrde/ext/gcc/configure --prefix=~lrde/usr/gcc-3.4 --enable-languages=c,c++ : (reconfigured) /home/lrde/stud/burrus_n/work/lrde/ext/gcc/configure --prefix=~lrde/usr/gcc-3.4 --enable-languages=c,c++ : (reconfigured) /home/lrde/stud/burrus_n/work/lrde/ext/gcc/configure --prefix=/home/lrde/lrde/usr/gcc-3.4 --enable-languages=c,c++
How-To-Repeat:
Compile this code with -Wreturn-type:
template <class T>
struct A
{
int foo()
{
throw "Stop";
}
};
------- Additional Comments From nicolas dot burrus at lrde dot epita dot fr 2003-07-30 13:22 -------
Fix:
Add -Wno-return-type if you want to keep -W.

I can confirm this on the mainline (20030730).
Fom Phil's Regression hunter: Search converges between 2002-12-17-trunk (#167) and 2002-12-
18-trunk (#168). This is the time when the new parser came in.

Actually I was wrong this is not caused by the new parser at all but rather this patch: <http://
gcc.gnu.org/ml/gcc-patches/2002-12/msg00944.html>. Jason you caused the regression, could
you look into it?

Basically when processing templates, it should mark the functions as returns abnormally
when using creating the throw, I will look into if Jason does not fix this regression soon.
