Bug ID: 65501 Summary: v850 ICE at c_register_pragma_1, at c-family/c-pragma.c:1317 Product: gcc Version: 5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: joel at gcc dot gnu.org This occurs during the exception model probe for libstdc++-v3. This should be reproducible on v850-elf. I think this is the conftest.c based on the aclocal.m4 file: cat > conftest.$ac_ext << EOF [#]line __oline__ "configure" struct S { ~S(); }; void bar(); void foo() { S s; bar(); } configure:15092: checking for exception model to use configure:15133: /users/joel/test-gcc/b-v850-rtems4.11-gcc/./gcc/xgcc -shared-libgcc -B/users/joel/test-gcc/b-v850-rtems4.11-gcc/./gcc -nostdinc++ -L/users/joel/test-gcc/b-v850-rtems4.11-gcc/v850-rtems4.11/libstdc++-v3/src -L/users/joel/test-gcc/b-v850-rtems4.11-gcc/v850-rtems4.11/libstdc++-v3/src/.libs -L/users/joel/test-gcc/b-v850-rtems4.11-gcc/v850-rtems4.11/libstdc++-v3/libsupc++/.libs -nostdinc -B/users/joel/test-gcc/b-v850-rtems4.11-gcc/v850-rtems4.11/newlib/ -isystem /users/joel/test-gcc/b-v850-rtems4.11-gcc/v850-rtems4.11/newlib/targ-include -isystem /users/joel/test-gcc/gcc/newlib/libc/include -B/users/joel/test-gcc/install-head/v850-rtems4.11/bin/ -B/users/joel/test-gcc/install-head/v850-rtems4.11/lib/ -isystem /users/joel/test-gcc/install-head/v850-rtems4.11/include -isystem /users/joel/test-gcc/install-head/v850-rtems4.11/sys-include -c -S conftest.cpp >&5 <built-in>: internal compiler error: in c_register_pragma_1, at c-family/c-pragma.c:1317 0x6a15f7 c_register_pragma_1 ../../gcc/gcc/c-family/c-pragma.c:1317 0x6a2fa6 c_register_pragma(char const*, char const*, void (*)(cpp_reader*)) ../../gcc/gcc/c-family/c-pragma.c:1335 0x534013 init_cp_pragma ../../gcc/gcc/cp/lex.c:225 0x534013 cxx_init() ../../gcc/gcc/cp/lex.c:276 0x435493 lang_dependent_init ../../gcc/gcc/toplev.c:1845 0x435493 do_compile ../../gcc/gcc/toplev.c:2062 Please submit a full bug report, with preprocessed source if appropriate.
