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

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.
