Bug ID: 117227 Summary: Missing modula2 plugin dependencies Product: gcc Version: 15.0 Status: UNCONFIRMED Severity: minor Priority: P3 Component: modula2 Assignee: gaius at gcc dot gnu.org Reporter: tschwinge at gcc dot gnu.org Target Milestone: --- I like doing incremental GCC builds, which generally works fine (within reason, of course). Recently I ran into a case where some GCC diagnostics changes had gone in, and after that, 'make check-gcc-m2' had ~100 '[-PASS:-]{+FAIL:+}' regressions, due to: *** WARNING *** there are active plugins, do not report this as a bug unless you can reproduce it without enabling any plugins. Event | Plugins PLUGIN_FINISH | m2rte during GIMPLE pass: runtime_exception_inevitable In function ‘_M2_modulusoverflow_fini’: cc1gm2: internal compiler error: tree check: expected tree that contains ‘identifier’ structure, have ‘function_decl’ in examine_function_decl, at m2/plugin/m2rte.cc:210 0x21702e5 internal_error(char const*, ...)

Therefore, I conclude that there are some missing modula2 plugin dependencies; 'gcc/m2/Make-lang.in:plugin/m2rte$(soext)' or thereabouts?
