Summary: libiberty demangle.test failure: strtod() on
sparc-sun-solaris2.9 does not accept hexadecimal
numbers
Product: binutils
Version: 2.26 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org

make: *** [check-d-demangle] Error 1
This is because Solaris 9 strtod() complies to SUSv2 and does not accept
hexadecimal parameters; see Application Usage section of POSIX:
http://pubs.opengroup.org/onlinepubs/9699919799/toc.htm
This simple test program:
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
double strtod(const char *str, char **endptr);
int
main()
{
double a;
char *endptr;
int c;
errno = 0;
a = strtod("0x0A8P6Zv", &endptr);
c = errno;
fprintf(stderr, "endptr = %s\n", endptr);
fprintf(stderr, "a = %g, errno = %d\n", a, c);
return 0;
}
produces
endptr = x0A8P6Zv
a = 0, errno = 0
on modern systems is produces
endptr = Zv
a = 10752, errno = 0
