Subject [jira] Commented: (STDCXX-828) [AMD64] SIGABRT in 27.istream.fmat.arith
Date Fri, 11 Apr 2008 23:23:04 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12588167#action_12588167
] 

Martin Sebor commented on STDCXX-828:
-------------------------------------

The following program reproduces the failing call with the argument values extracted from
the stack trace. When compiled with gcc 4.1.1 on Linux/x86_64 as show, it produces the expected
output (see below).

{noformat}
$ cat t.cpp && make t && CLASS="basic_istream<char, UserTraits<char>>"
./t
#include <rw_printf.h>

int main ()
{
    rw_fprintf (0,
                "%{$FUNCALL!:@}",
                "%{$CLASS}(%{*Ac}).operator>>(%s& = %{@}): "
                "initial flags() = %{If}, rdstate() = %{Is}, "
                "exceptions() = %{Is}, whitespace = %{#s}, numpunct = { "
                ".dp=%{#c}, .ts=%{#c}, .grp=%{#s}, .fn=%{#s}, .tn=%{#s} }",
                1, " ", "long double", "%Lg", 9.0L,
                671289346, 0,
                0, " ", -1, -1, (void*)0, (void*)0, (void*)0);

    rw_printf ("%{$FUNCALL}\n");
}

basic_istream<char, UserTraits<char>>(" ").operator>>(long double& =
9): initial flags() = dec | skipws | nolock | nolockbuf, rdstate() = goodbit, exceptions()
= goodbit, whitespace = " ", numpunct = { .dp='\xff', .ts='\xff', .grp=(null), .fn=(null),
.tn=(null) }
{noformat}

When compiled with Sun C++ 5.8 on Solaris 10/AMD64 in 15S mode, the program produces the following
bogus output (the value of the funky '�' character is octal 377):
{noformat}
basic_istream<char, UserTraits<char>>(" ").operator>>(long double& =
1.69954e-4944): initial flags() = 0x600000 | dec | uppercase | nolock | nolockbuf� | base(2,
rdstate() = 0x28031000 | eofbit, exceptions() = goodbit, whitespace = (null), numpunct = {
.dp='g', .ts='\xff', .grp=(invalid address 0xfffffd7fffffffff), .fn=(null), .tn=(null) }
{noformat}

>                 URL: https://issues.apache.org/jira/browse/STDCXX-828
>             Project: C++ Standard Library
>          Issue Type: Bug
>          Components: Tests
>    Affects Versions: 4.2.0
>         Environment: Sun C++ 5.9/Solaris/AMD64
>            Reporter: Martin Sebor
>            Assignee: Eric Lemings
>             Fix For: 4.2.1
>
>         Attachments: 27.istream.fmat.arith.cpp
>
>   Original Estimate: 4h
>          Time Spent: 8h
>  Remaining Estimate: 2h
>
> When compiled with Intel C++ 10.0 on Linux/AMD64 or Sun C++ 5.9 on Solaris 10/AMD64,
the test [27.istream.fmat.arith.cpp|http://svn.apache.org/repos/asf/stdcxx/trunk/tests/iostream/27.istream.fmat.arith.cpp]
abends with SIGABRT. This was observed in 8{D,S}, 12{D,S} and 15D build types, not necessarily
consistently on both platforms.
> The same test was also failing in 4.2.0 with Intel C++.
