Summary: libstdc++-4.3 21_strings/basic_string/capacity/char/18654.cc test on fdpic would fail
Details:
libstdc++-4.3 21_strings/basic_string/capacity/char/18654.cc test on fdpic would fail frequentlynow. It looks has something related to the hush return code issue, need verification.
Tests that now fail, but worked before:

Follow-ups
--- Jie Zhang 2010-01-26 09:05:22
I cannot reproduce it.
--- Vivi Li 2010-07-01 03:17:54
I also see this bug happening on some regression machine for bfin-linux-uclibc.
--- Vivi Li 2010-07-08 03:35:21
From the log on target board, I can see when this execution test fail, there is
a page allocation failure on target board.

The test in this case:
const size_type maxsize = 2 << 20; /* 1Meg */
for (size_type i = minsize; i <= maxsize; i *= 2)
{
string str(i, 'x');
str.reserve(3 * i);
str.reserve(2 * i);
VERIFY( str.capacity() == 2 * i );
str.reserve();
VERIFY( str.capacity() == i );
}
Which will try to malloc 4Meg - so that explains the order 11 allocation (8Meg
page)
Most likely works with:
- const size_type maxsize = 2 << 20;
+ const size_type maxsize = 2 << 16;
--- Stuart Henderson 2010-08-04 11:27:16
The test will often pass as there is enough memory, however, during testing the
memory is becoming quite badly fragmented and we end up with no areas large
enough. There's nothing we can realistically do about this other than Robin's
suggested change, so I'm going to recommend we just go with that.
Unless anyone objects, i'll update the test.
--- Stuart Henderson 2010-08-09 05:24:54
Fixed the test. It's still possible the test could fail, but it's significantly
less likely.
--- Vivi Li 2010-08-24 05:57:45
Yes, it's better now.
Close it.
--- Mingquan Pan 2011-11-04 05:58:30
I reopen this for I have seen the 18654 case has made kernel panic sometimes
when testing on linux-uclibc,and the board reset introduces more failure in
libstdc++ testing.
FAIL: 21_strings/basic_string/capacity/wchar_t/18654.cc execution test
It could be this case make this bug.

Have a lot of fun...
The detailed log is attached.
This case also fails on bf527, but it didn't make kernel panic and the produced
log is ok.
If we make the change as in checkin 4784 ( which is applied to
21_strings/basic_string/capacity/char/18654.cc) too, then this case can also
pass on bf537 stamp board.
I run 18654 for two times, the first one is before the change, the second one
is after the change.

So shall we also apply the change to this case ,either?
