--- Comment #58 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
So we have the dreaded mix of 11.x Ada exception code and 10.x unwind code:
#0 0x773bb68b in msvcrt!abort () from C:\WINDOWS\SysWOW64\msvcrt.dll
#1 0x02074f7d in uw_init_context_1 (context=context@entry=0x1070c890,
outer_cfa=outer_cfa@entry=0x1070ca70,
outer_ra=0x406f8a <__gnat_Unwind_RaiseException(_Unwind_Exception*)+17>)
at ../../../gcc-10.3.0/libgcc/unwind-dw2.c:1593
#2 0x01e2ba3d in _Unwind_RaiseException (exc=0x132d8a90)
at ../../../gcc-10.3.0/libgcc/unwind.inc:93
#3 0x00406f8a in __gnat_Unwind_RaiseException (e=e@entry=0x132d8a90)
at ../../gcc-11.2.0/gcc/ada/raise-gcc.c:1391
On the one hand, this should no longer exist on the mainline but, on the other
hand, this has never been problematic for AdaCore's internal builds.
