Summary: thousands grouping bug when rounding requires an extra
leading digit
Product: glibc
Version: 2.12
Status: NEW
Severity: normal
Priority: P2
Component: localedata
AssignedTo: libc-locales@sources.redhat.com
ReportedBy: ajschorr@alumni.princeton.edu
Created attachment 5191
--> http://sourceware.org/bugzilla/attachment.cgi?id=5191
C code to demonstrate the bug
The attached program printthou.c gives buggy results:
bash-4.1$ echo 999.999 999999.999 | printthou
1000.00
,000,000.00
The program is using printf with the format "%'.2f". As you can
see, those inputs expose bugs in the logic.
These inputs give the expected results:
bash-4.1$ echo 1000 1000000 | printthou
1,000.00
1,000,000.00
Regards,
Andy

Oops, I should mention that I see the problem with LC_NUMERIC="en_US.UTF-8".
It works fine in C locale:
bash-4.1$ echo 999.999 999999.999 | LC_NUMERIC=C printthou
1000.00
1000000.00
bash-4.1$ echo 999.999 999999.999 | LC_NUMERIC=en_US.UTF-8 printthou
1000.00
,000,000.00

The bug affects not only the %f directive, but also the %g directive,
and can lead to a segmentation fault in the latter case.
Find attached the test case. How to reproduce:
$ gcc -Wall bug12394.c
$ ./a.out
Segmentation fault (core dumped)
$ gdb a.out core
(gdb) where
#0 0x00007f70364aeaa4 in __printf_fp () from /lib64/libc.so.6
#1 0x00007f70364a9b4d in vfprintf () from /lib64/libc.so.6
#2 0x00007f70364cbee9 in vsprintf () from /lib64/libc.so.6
#3 0x00007f70364b2118 in sprintf () from /lib64/libc.so.6
#4 0x0000000000400819 in main ()
