It appears that
switch success case 0 { invalid() }causes a bug in the snarks solidity templates that emerges aswhen the curve pairing fails.
The following remix debug gives some more insight into this issue:
{ "error": "Failed to decode output: Error: hex data is odd-length (argument=\"value\", value=\"0x0\", code=INVALID_ARGUMENT, version=bytes/5.5.0)" }My guess is that the curve pairing returns
0x0or0x1which cannot be handled inside the assembly.
