It turns out there was one more bug in the earlier complex series: read_base_type could cause an assertion failure on some platforms. I found this running the AdaCore internal test suite, but you can also see it by running gdb's "gdb.cp" tests for x86 (not x86-64). In particular, the DW_ATE_complex_float case calls dwarf2_init_complex_target_type, which calls dwarf2_init_float_type, which can return a type using TYPE_CODE_ERROR. This patch changes the DWARF reader to handle this case, the same way that the f-lang.c patch did. Perhaps init_complex_type really should be changed to allow TYPE_CODE_ERROR? I was not sure. Tested on x86-64 Fedora 30, using an x86 build. I'm checking this in. gdb/ChangeLog 2020-04-06 Tom Tromey <tromey@adacore.com> * dwarf2/read.c (read_base_type) <DW_ATE_complex_float>: Handle TYPE_CODE_ERROR.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
