Here's a (symmetric) testcase that crashes mainline: ============================ ;int foezis = sizeof tni; ============================ :1:c.c:1: error: 'tni' undeclared here (not in a function) :1:c.c:1: internal compiler error: tree check: expected class 't', have 'x' (error_mark) in c_expr_sizeof_expr, at c-typeck.c:1854 Please submit a full bug report, [etc.]
: Search converges between 2004-09-07-trunk (#536) and 2004-09-10-trunk (#537). Confirmed.
looks like Joseph is to blame...?
