             Bug #: 50274
           Summary: Conditionnal rethrow
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: romain.geissler@gmail.com


This bug could be reproduced on x86_64 with G++ 4.5.x, 4.6.x and the current
trunk.

Target: x86_64-unknown-linux-gnu
Configured with: /prj/compwork2/geissler/trunk/configure
--prefix=/prj/compwork2/geissler/install --enable-shared
--enable-languages=c,c++ --disable-libgcj --enable-checking --enable-plugin
--with-gmp=/sw/st/gnu_compil/gnu/linux-rh-ws-4-x86_64/
--with-mpfr=/sw/st/gnu_compil/gnu/linux-rh-ws-4-x86_64/
--with-mpc=/sw/st/gnu_compil/gnu/linux-rh-ws-4-x86_64/
--with-ppl=/sw/st/gnu_compil/gnu/linux-rh-ws-4-x86_64/
--with-cloog=/sw/st/gnu_compil/gnu/linux-rh-ws-4-x86_64/
Thread model: posix
gcc version 4.7.0 20110829 (experimental) (GCC)

Compilation line: g++ rethrow.cpp -o rethrow

The rethrow made in foo handler is not caught by the main handler as it should.
Here is the execution trace:
throw
caught foo
terminate called after throwing an instance of 'int'
Aborted

It works with GCC 4.4.x :
throw
caught foo
caught main

If the test "if (!i)" is removed, it works. If foo prototype is changed to
return void it also works.
