[Bug libmudflap/22155] New: ICE with: "-fmudflap -D_GLIBCXX_DEBUG"

[ctsa at u dot washington dot edu]

I get an ICE for gcc 4.0.0 when trying to use mudflap and libstdc++ debug mode
together; This is the smallest testcase I could make:

test.cc:
"""
#include <vector>

struct S { unsigned i; };

void g(const unsigned u, std::vector<unsigned>& s);

void f(const S& s) {
  std::vector<std::vector<unsigned> > t(1);
  g(s.i,t[0]);
}
"""

$ g++ -D_GLIBCXX_DEBUG -fmudflap -c test.cc
test.cc: In function 'void f(const S&)':
test.cc:7: internal compiler error: Segmentation fault
