--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Thanks - so it looks as though the problem is in std::stod which is pretty
simple, and can be reduced to:
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
int main()
{
double d;
char* endptr;
errno = 0;
const char* str = "0x1.1000000000000p+8";
const double tmp = strtod(str, &endptr);
if (endptr == str) {
puts("no characters consumed");
return 1;
}
else if (errno == ERANGE) {
puts("ERANGE");
return 2;
}
else if (*endptr) {
printf("stopped at '%c'\n", *endptr);
return 3;
}
else
d = tmp;
printf("%f %a\n", d, d);
}
Maybe Solaris' strtod() doesn't support hex floats in C++ code, so it will
print "stopped at 'x'"
