--- Comment #14 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > FYI, to make you an idea of the c380004's failure, a SEGV occurs in > cygwin.S:___chkstk_ms, caused by stack check at c380004.adb:132. Ah, yes, it's a known issue on 64-bit Windows. Both tests are pathological and require more than 2 MB of stack to pass on 64-bit platforms, so the special pragma Link_With in s-taprop-mingw.adb would need to be bumped to 0x400000.
