[rodrigc@gcc.gnu.org]

Synopsis: ICE in gcc-3.0.2 during compilation of cyclone

State-Changed-From-To: open->analyzed
State-Changed-By: rodrigc
State-Changed-When: Mon Nov 19 19:31:50 2001
State-Changed-Why:
    Confirmed with gcc 3.0.2 and gcc 3.0 branch.
    Note:
    The problem does not occur if compiled with the C++ compiler.
    
    Also, under gcc 3.1, this problem does not seem to occur.
    
    If I run cc1plus under a debugger, the stack trace I get is:
