> [EDG C++ 3.9] definition of jmp_buf causes buffer overflow
> ----------------------------------------------------------
>
> Key: STDCXX-989
> URL: https://issues.apache.org/jira/browse/STDCXX-989
> Project: C++ Standard Library
> Issue Type: Bug
> Components: 18. Language Support
> Affects Versions: 4.2.x
> Environment: Linux/EDG C++ 3.9
> Reporter: Travis Vitek
> Assignee: Martin Sebor
> Fix For: 4.2.x
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The {{jmp_buf}} definition provided in {{include/ansi/\_csetjmp.h}} is not as
> large as {{setjmp()}} is expecting. This causes a buffer overflow when
> running tests that use the test driver ({{rw_test}}), which results in data
> corruption. If you run the tests with {{--trace}}, you will see that the
> _clause_ field of the output is always corrupt after the first use.
> The following shows the expected size for us...
> {noformat}
> $ cat u.cpp; eccp u.cpp && ./a.out
> #include <setjmp.h>
> #include <stdio.h>
> int main ()
> {
> printf ("%u\n", sizeof (jmp_buf));
> return 0;
> }
> 156
> {noformat}
> The definition of {{jmp_buf}} in {{include/rw/_csetjmp.h}} is a buffer of 8
> bytes.
