I'm trying to debug a core dump from GoldenCheetah which has been
compiled with clang++ on OpenBSD 6.4 amd64.
gdb fails like this:
$ gdb /usr/local/bin/GoldenCheetah GoldenCheetah.core
GNU gdb 6.3
...
[[loading lots of shared (qt) libraries]]
...
Loaded symbols for /usr/local/lib/libwebpdemux.so.2.0

Dwarf Error: Cannot find type of die [in module /usr/local/bin/GoldenCheetah]

Dwarf Error: Cannot find type of die [in module /usr/local/bin/GoldenCheetah]
and lldb crashes:
$ lldb -c GoldenCheetah.core /usr/local/bin/GoldenCheetah
(lldb) target create "/usr/local/bin/GoldenCheetah" --core "GoldenCheetah.core"
Bus error
/var/log/messages shows:
/bsd: coredump of lldb(5642), write failed: errno 14
Any suggestion how I can debug that program? (it's huge and written
in C++ with which I am not familiar anyway :-(
