Bug ID: 79509 Summary: m68k/coldfire: Internal error, aborting at dw2gencfi.c:214 in emit_expr_encoded Product: gcc Version: 6.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: wbx at openadk dot org Target Milestone: --- At least three packages in Buildroot are failing with this Internal Error for m68k/coldfire target. GCC 6.3, Binutils 2.26.1 is in use. The problem can be avoided by using -fno-dwarf2-cfi-asm in CXXFLAGS. The packages failing are: kmsxx from https://github.com/tomba/kmsxx lcdapi from https://github.com/spdawson/lcdapi libasplib from https://github.com/AchimTuran/asplib Not sure how to provide a simple test case. It seems only to happen for C++ applications/libraries.
