The following testcase ICEs (the embed one actually doesn't but
dereferences random uninitialized pointer far after allocated memory)
because of a typo. In the RAW_DATA_CST handling of list conversion
where there are conversions to something other than
initializer_list<{{,un}signed ,}char>, the code now calls
implicit_conversion for all the RAW_DATA_CST elements and stores them
into subsubconvs array.
The next loop (done in a separate loop because subsubconvs[0] is
handled differently) attempts to do the
for (i = 0; i < len; ++i)
{
conversion *sub = subconvs[i];
if (sub->rank > t->rank)
t->rank = sub->rank;
if (sub->user_conv_p)
t->user_conv_p = true;
if (sub->bad_p)
t->bad_p = true;
}
rank/user_conv_p/bad_p merging, but I mistyped the index, the loop
iterates with j iterator and i is subconvs index, so the loop effectively
doesn't do anything interesting except for merging from one of the
subsubconvs element, if lucky within the subsubconvs array, if unlucky
not even from inside of the array.
The following patch fixes that.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
