[LLVMdev] "Duplicate option categories" assertion triggered loading an LLVM-project

[Alberto Magni]

Hello Sergey,

thanks for the suggestion.

The name of the pass is not what triggers the assertion.
The test case I attached to the email is a stripped-down version of a much
more complicated pass
(with a proper name) that originally caused the problem.

Also, to be sure, I just tried to change the name of the pass to something
more significant.
It did not work.

Cheers,
Alberto
