You're right, it was fixed by
Revision 141193 - (view) (download) - [select for diffs]
Modified Fri Oct 17 14:50:07 2008 UTC (12 days, 9 hours ago) by krebbel
File length: 238566 byte(s)
Diff to previous 140914 (colored)
2008-10-17 Andreas Krebbel <krebbel1@de.ibm.com>
* c-parser.c (c_parser_binary_expression): Silence the
uninitialized variable warning emitted for binary_loc.
I hadn't noticed because I started adding --disable-werror to my configuration
files.
Closing as fixed.
