Subject: [PATCH] Fix reading of the first parameter
|
|
|
|
This is a fixup for 7b8b5eb4eac314a3a29be812bef0264c6611f6e7.
|
|
Previously, it would return as long as the parameter was _not_ seen
|
|
before. It also did not handle the case for the unsupported opcode (-1)
|
|
which would cause a segfault when accessing the "seen" array.
