--- Comment #21 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain D Sandoe <ia...@gcc.gnu.org>: https://gcc.gnu.org/g:ec6d1fc09faea4a6be4df74babb73dca6b50ff0c commit r13-4996-gec6d1fc09faea4a6be4df74babb73dca6b50ff0c Author: Iain Sandoe <i...@sandoe.co.uk> Date: Fri Dec 30 19:46:13 2022 +0000 modula-2: Fix registration of modules via constructors [PR108183]. This reworks the mechanism used for module registration to use init- time constructors. The order of registration is not important, the actual initialization dependency tree will be computed early in the execution (all that matters is that we have registered before that). This fixes a potential issue in which the external name known to the m2 system is of the form _M2_XXXXXX_ctor() but the C++ code was producing a static variable instance with the same name.
