Subject: [newlib-cygwin] stdio: Parse 0x0p+00 correctly in scanf
Date: Fri, 18 Jun 2021 21:15:48 +0000 (GMT)	[thread overview]
Message-ID: <20210618211548.03A3E383303A@sourceware.org> (raw)

https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=92068f4cc5f2cb655b32a46fdba93a9e572c307b

commit 92068f4cc5f2cb655b32a46fdba93a9e572c307b
Author: Keith Packard <keithp@keithp.com>
Date:   Fri Jun 18 11:09:48 2021 -0700

    stdio: Parse 0x0p+00 correctly in scanf
    
    The scanf code was skipping the '0' after the 'x' causing the
    resulting buffer to contain an invalid number when passed to strtod.
