0001416: 22446: unknown sizes of types and value initialization
Commit 22446 transforms a crash when some types have unknown sizes into a clean exit, but there remains a problem with the test below: Sending src/value/initial_state.ml Transmitting file data . Committed revision 22446. ~/ppc $ cat t.c struct s; struct larger { struct s t[2]; int i; } v; int main(int c, char **v) { return 0; } ~/ppc $ bin/toplevel.opt -val t.c [kernel] warning: cannot load 5 plug-ins (incompatible with Fluorine-20130401+dev).
