[Bug c++/17655] New: g++ getting SEGFAULT compilling the code with HUGE_VAL comparasions

["programm at metrocom dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

gcc crashes compiling the following code:

(cmdline is g++-3.4 test.cc)

extern "C" {
#include <math.h>
};

template<typename T> void GetFromString()
{
    if (HUGE_VAL) {};
    // The same result as above
    // if (10.0 == HUGE_VAL) {};
};

int main(char argc, char** argv)
{
  GetFromString<char>();
};

It reports:

test.cc: In function `void GetFromString() [with T = char]':
test.cc:14:   instantiated from here
test.cc:7: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

g++ -v output:
