            Bug ID: 62231
           Summary: Exception handling broken on
                    powerpc-e500v2-linux-gnuspe
           Product: gcc
           Version: 4.8.3
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: manfred.rudigier at omicron dot at

Problem:
--------

The GCC exception handling mechanism for powerpc-e500v2-linux-gnuspe seems to
be broken. Every programs abort as soon as the first exception is thrown. I can
confirm that the exception handling works on at least 4.6.3 and 4.7.4, however
on 4.8.3 it does not.

Example program to reproduce the problem:
-----------------------------------------

#include <exception>
#include <stdio.h>

void doThrow()
{
    printf("Throwing now\n");
    throw std::exception();
}

int main(int argc, char **argv)
{
    try {
        doThrow();
    } catch (std::exception& e) {
        printf("Caught exception\n");
    }
    return 0;
}


GDB output:
-----------

Program received signal SIGABRT, Aborted.
0x0fc0c858 in raise () from /lib/libc.so.6
(gdb) bt
#0  0x0fc0c858 in raise () from /lib/libc.so.6
#1  0x0fc117c4 in abort () from /lib/libc.so.6
