Iain Sandoe <iains at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2022-12-26 Ever confirmed|0 |1 --- Comment #1 from Iain Sandoe <iains at gcc dot gnu.org> --- it seems that this is fallout from a recent change in the trunk libgcc unwinder (which we should not be using on Darwin) fixed by: r13-4870-ga846817739c1e7b930d593cd51963d6b46b5dfc6 r13-4883-g163f0f2267370575a9950e7e30a2c9cd72f559f0 and https://gcc.gnu.org/pipermail/gcc-patches/2022-December/609110.html fix this by ensuring that we do not try to use the newly-built libgcc_s unwinder for Ada executables that also pull in system libraries that refer to the installed unwinder).
