--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note without RTL checking we get:
```
<source>:7:3: error: impossible constraint in 'asm'
7 | __asm__ goto("" : "=r"(bitint0) : : : lab);
| ^~~~~~~
<source>:8:1: error: wrong number of branch edges after unconditional jump in
bb 5
8 | }
| ^
<source>:8:1: error: wrong number of branch edges after unconditional jump in
bb 3
during RTL pass: cse1
dump file: /app/output.cpp.272r.cse1
<source>:8:1: internal compiler error: verify_flow_info failed
0x2332cfc internal_error(char const*, ...)
???:0
0xb27bd3 verify_flow_info()

Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
```
With release checking we get an ICE after the first error; the `confused by
earlier errors, bailing out`.
