Figured out I overlooked the Compiler Options/Verbosity settings for
some reason.
Setting verbosity to -va and keeping the package options "generate debug
info" (-g) and line numbers (-gl) gives:
... a lot of output...
lr_class.pas(11454,3) Note: Local variable "wValue" not used

Hmmm? dbgstabs.pas suggests something to do with generating debug info
perhaps?

-va and no -g -gl does let Lazarus compile the package.

Perhaps the problem lies with the compiler instead of Lazreport?
