--- Comment #1 from Pedro Alves <palves at redhat dot com> ---
With current master, I get:
$ gdb -ex "demangle -l c++
__020A___________________X00020A___R0020A__U000R03000N99999999_020A__K000"
GNU gdb (GDB) 7.12.50.20160808-git
[...]
/home/pedro/gdb/mygit/src/gdb/utils.c:1096: internal-error: virtual memory
exhausted: can't allocate 2147483647 bytes.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
(and it takes quite a bit to reach that.)
Is this expected? AFAICS, the relevant patches mentioned in gcc PR69687 have
been merged to gdb/binutils master already.
