Hi Tom,
The all-architectures tests (e.g. gdb.base/all-architectures-2.exp) started failing
after the commit (5b930b4538f "Change how complex types are created") because of an
assertion.
A manual way to reproduce the cause is
$ gdb -q
(gdb) set architecture c5
The target architecture is assumed to be c5
(gdb) ptype 1.0L
type = /gdb/gdbtypes.c:3037: internal-error: type* init_complex_type(const char*, type*): Assertion `TYPE_CODE (target_type) == TYPE_CODE_INT || TYPE_CODE (target_type) == TYPE_CODE_FLT' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
This GDB was configured with --enable-targets=all.
Thanks.
