--- Comment #68 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Eric Botcazou <ebotca...@gcc.gnu.org>: https://gcc.gnu.org/g:8fe93cc664ded8cc1952da28b23f3fc68504a73e commit r12-4530-g8fe93cc664ded8cc1952da28b23f3fc68504a73e Author: Arnaud Charlet <char...@adacore.com> Date: Wed Oct 20 10:23:40 2021 +0200 Avoid exception propagation during bootstrap This addresses PR ada/100486, which is the bootstrap failure of GCC 11 for 32-bit Windows in the MSYS setup. The PR shows that we cannot rely on exception propagation being operational during the bootstrap, at least on the 11 branch, so fix this by removing the problematic raise statement. gcc/ada/ PR ada/100486 * sem_prag.adb (Check_Valid_Library_Unit_Pragma): Do not raise an exception as part of the bootstrap.
