Hi guys, Does any of you know how to go about submitting an Intel compiler bug without a premier support account?
While configuring the library on my x86_64 machine, I ran into what appears to be a code generation compiler bug which affects LIMITS.cpp test -- the test cycles ad infinitum because of the incorrect test marked below: $ uname -a; icpc -v; cat t.cpp; icpc t.cpp && ./a.out Linux behemoth 2.6.37.6 #3 SMP Sat Apr 9 22:49:32 CDT 2011 x86_64 AMD Opteron(tm) Processor 6134 AuthenticAMD GNU/Linux icpc version 12.1.5 (gcc version 4.5.2 compatibility) #include <stdio.h> volatile int zero = 0; volatile int one = zero + 1; volatile int two = one + 1; template< typename T > T test () { T max = T (one); // Find largest in which multiplied by two results in a // negative value for (; T (max * two) > max; max *= two) ; // // Perform a binary search variant for the maximum // T tmp = max / (two + two); for (; tmp;) { if (T (max + tmp) < max) { // <- fail if (tmp > T (two)) tmp /= two; else if (max < T (max + one)) tmp = one; else break; } else max += tmp; } return max; } int main () { printf ("INT_MAX : %x\n", test< int > ()); return 0; } ^C $ which runs just fine with gcc: $ g++ t.cpp && ./a.out INT_MAX : 7fffffff Thanks!
