--- Comment #1 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain Buclaw <ibuc...@gcc.gnu.org>: https://gcc.gnu.org/g:074b2b0f91f948fe3488ada91ec6a8576c684dea commit r15-9485-g074b2b0f91f948fe3488ada91ec6a8576c684dea Author: Iain Buclaw <ibuc...@gdcproject.org> Date: Tue Apr 15 15:19:13 2025 +0200 d: Fix internal compiler error: in visit, at d/decl.cc:838 [PR119799] This was caused by a check in the D front-end disallowing static VAR_DECLs with a size `0'. While empty structs in D are give the size `1', the same symbol coming from ImportC modules do infact have no size, so allow C variables to pass the check as well as array objects. PR d/119799 gcc/d/ChangeLog: * decl.cc (DeclVisitor::visit (VarDeclaration *)): Check front-end type size before building the VAR_DECL. Allow C symbols to have a size of `0'. gcc/testsuite/ChangeLog: * gdc.dg/import-c/pr119799.d: New test. * gdc.dg/import-c/pr119799c.c: New test.
