[Bug c++/26186] New: internal compiler error in template resolution

[smirolo at hotmail dot com]

I've got a complex template expression which produces an internal error into
gcc. By chance I tried on the native Mac gcc-4.0.0 and it gaves me  correct
error messages as the templates are not qualified correctly. Nonetheless, I
think it is worth reporting for future regression tests.

Sebastien.

On the mainline I get:
testLatency.cc:8: error: invalid use of 'class sideParms<s>'

I can reproduce the ICE on i686 with 3.4.4, but it seems to be fixed with
g++ (GCC) 3.4.6 20060110 (prerelease) which tells us

testLatency.cc: In function `latency latencyOf(size_t, widthTag, widthTag,
int)':
testLatency.cc:8: error: invalid use of `class sideParms<s>'

For some reason I don't have 3.4.5, so I'm unsure about the target milestone
where this is fixed (just saying 3.4.6 for now).

Actually it's already fixed in 3.4.5.
