Frank,
I've narrowed things down to one particular rule. It seems that the
following rule with all of its alternatives is causing problems.
scoped_identifier:
TOK_IDENTIFIER
{
}
|
TOK_SCOPE_OPERATOR TOK_IDENTIFIER
{
}
|
scoped_identifier TOK_SCOPE_OPERATOR TOK_IDENTIFIER
{
}
;
If I simplify this rule to the following, I do not have any problems
with semantic values not being saved on the stack correctly.
scoped_identifier:
TOK_IDENTIFIER
{
}
;
It seems that these extra alternatives are confusing the parser. Do you
have any idea why this could be?
Thanks,
Dallas
