[Bug libc/4362] New: printf segfaults on some fp values

[aurelien at aurel32 dot net]

The following programs segfaults on the last printf(). Using the commented 
variable does not trigger the problem.

This problem happens with glibc CVS and glibc 2.5, but not on glibc 2.3.6. This 
bug has been tested so far on x86, x86_64 and sparc, but I suspect all 
platforms are affected.

#include <stdio.h>
int main() {
        //double a=0.00999624628294258;
        double a=9.99624628294258e-05;
        printf("e: %e\n", a);
        printf("f: %f\n", a);
        printf("g: %g\n", a);
        printf("e: %.3e\n", a);
        printf("f: %.3f\n", a);
        printf("g: %.3g\n", a);
        return 0;
}
