This assertion was hit because of bogus DWARF generated by the Intel Fortran compiler. While that compiler should fix the DWARF, we prefer GDB to error out here instead, e.g. to allow the user to continue debugging other parts of the program. --- gdb/value.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/gdb/value.c b/gdb/value.c index 8840aa41a33..a67e696ae4f 100644 --- a/gdb/value.c +++ b/gdb/value.c @@ -3056,7 +3056,9 @@ value::primitive_field (LONGEST offset, int fieldno, struct type *arg_type) gdb_assert (0 == offset); /* We expect an already resolved data location. */ - gdb_assert (TYPE_DATA_LOCATION (type)->is_constant ()); + if (PROP_CONST != TYPE_DATA_LOCATION_KIND (type)) + error (_("cannot read %s, expected an already resolved data " + "location."), arg_type->field (fieldno).name ()); /* For dynamic data types defer memory allocation until we actual access the value. */ v = value::allocate_lazy (type); -- 2.34.1 Intel Deutschland GmbH Registered Address: Am Campeon 10, 85579 Neubiberg, Germany Tel: +49 89 99 8853-0, www.intel.de Managing Directors: Christin Eisenschmid, Sharon Heck, Tiffany Doon Silva Chairperson of the Supervisory Board: Nicole Lau Registered Office: Munich Commercial Register: Amtsgericht Muenchen HRB 186928
