Never mind. This is a bug in the newlib scanf family implementation
(actually, in __svfscanf_r in libc/stdio/vfscanf.c) that causes it to read
strings of the form 0x0+ incorrectly. Attached is a testcase that
demonstrates the bug. I suspect the following change:
2004-04-21 J"orn Rennecke <joern DOT rennecke AT superh DOT com>
* libc/stdio/vfscanf.c (NNZDIGITS): New define.
(__svfscanf_r): In integer conversions, leave out leading zeroes
which are not part of a base prefix.
Keep track of width truncation to fit into buf, not counting left-out
zeroes against width till the truncation has been compensated for.
HTH,
Igor
