Summary: GCC 4.2.1 [FreeBSD] segfaults with certain use of void
typedefs with debugging symbols
Product: gcc
Version: 4.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]

Test file showing the bug
The following makes GCC segfault:
namespace foo
{
typedef void Fvoid;
}
using foo::Fvoid;
int main()
{
return 0;
} // < segfault reported on this line
Note that the code should be compiled with debugging symbols activated (I've
tested with -g or -ggdb) - without them, the bug does not get triggered.
Namespaces can be nested deeper ("using foo::bar::Fvoid;") and the bug still
appears.
Merely using the type does NOT trigger a segfault:
// these do NOT segfault:
foo::Fvoid* v1;
using namespace foo;
Fvoid* v2;
Compile the test file with: g++ -g "test.cpp"
Error reported: test.cpp:25: internal compiler error: Segmentation fault: 11
