Dear Maintainer,
just tried to collect some more information.
I could reproduce the issue inside a qemu amd64 VM,
running current Buster.
Not every attempt resulted in a crash.
Indeed "file" seems to report just the first 80
character of the command line.
Like gdb does too when it opens a core file.
The full command line is shown by "coredumpctl gdb"
in my case, as I have installed systemd-coredump.
The actual crash looks like we expect there 320 entries in
the array syms, but that is now pointing to 0x0.
(gdb) print *symtab
$12 = {nsyms = 320, aux = 0x7f1370010a80, syms = 0x0, id =
5375926499655753679}
See more details in attached file.
Kind regards,
Bernhard
