Hi Harald,
please find attached an obvious patch by Steve for a technical
regression that resulted from improvements in error recovery
of bad uses of associate.
Regtested on x86_64-pc-linux-gnu.
Will commit soon unless there are comments.
Obvious enough, I think. Thanks!
As a sidenote: the testcase shows that we resolve the associate
names quite often, likely more often than necessary, resulting
in many error messages produced for the same line of code. In
the present case, each use of the bad name produces two errors,
one where it is used, and one at the associate statement.
That is probably not helpful for the user.
We have an "error" flag in gfc_expr, which we use infrequently to
avoid repetitions of errors. If an error has already been issued
for an expression, then we could set this. We would have to be careful
about resetting the error on matching though, so it is probably better
to only use it during resolution.
Best regards
Thomas
