EH unwind bug

[Thomas Weise <tom at zaphod dot wh9 dot tu-dresden dot de>]

egcs-2.90.18, i486-pc-linux-gnulibc1, libc-5.4.39

After latest EH fixes I've finally managed to provide a testcase for the
EH bug I've already reported. Building and runnings attached program
gives following:

tom@hermes:/home/tom > g++ -v
Reading specs from
/usr/local/lib/gcc-lib/i486-pc-linux-gnulibc1/egcs-2.90.18/specs
gcc version egcs-2.90.18 971122 (gcc2-970802 experimental)
tom@hermes:/home/tom > g++ bug.cc
tom@hermes:/home/tom > a.out
stackObj::~stackObj()
stackObj::~stackObj()
IOT trap/Abort

This is, the local object's destructor is executed twice, before the
exception raiser's destructor and again after raising the exception.
I hope it comes in time and can be fixed before release.

Tom.
