The compiler doesn't currently check that the width of an indexed part select is non-zero. If code contains this erroneous case, the compiler can crash (with an assertion failure). This patch causes the compiler to output a suitable error message and recover. It also fixes a potential crash if an illegal expresson is encountered.
This patch can be applied to both devel and v0.9.
I'm also attaching a patch which stops the compiler generating duplicate error messages for this condition. This second patch is for devel only.
Also attached is a regression test for the test suite. This test should produce a compile error.
