[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 Fix For: 4.2.x 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
