[Bug target/43460] New: internal compiler error: Segmentation fault on __builtin_unreachable() after asm goto()

["mirq-gccboogs at rere dot qmqm dot pl" <gcc-bugzilla at gcc dot gnu dot org>]

$ LANG=C /usr/src/gcc-armtest/bin/arm-none-eabi-gcc -c a.c 
a.c: In function 'main':
a.c:7:1: internal compiler error: Segmentation fault
[...]

$ cat a.c 
main()
{
    asm goto("" :::: test);
    __builtin_unreachable();
test:
    ;
}

It's the same with valid jump inside asm goto().

$ gcc -v
