Re: Bug: Remote reference (@>$1) doesn't work while ($LR1) works. [7.7]

[Carsten Dominik <carsten.dominik@gmail.com>]

Hi Wu Feng,

thank your for this rather clear bug report, even including the correct
analysis.  And Christian, thanks for confirming that this is a bug.

As already suggested by Wu Feng, this error is caused by a premature
expansion of @>$1, while still inside the context of table 2.  In that
context, @>$1 expands to @2$1 and then accesses the wrong field in
table 1.

This should be fixed now, please verify.

Thanks!

- Carsten
