Subject [jira] Updated: (STDCXX-1015) [gcc 4.3.0] ICE compiling VA_LIST.cpp config test
Date Wed, 06 May 2009 15:55:32 GMT

     [ https://issues.apache.org/jira/browse/STDCXX-1015?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martin Sebor updated STDCXX-1015:
---------------------------------

    Environment: gcc 4.2.x, 4.3.x, 4.4.0, x86_64  (was: gcc 4.3.0, 4.3.1)

The ICE occurs with all releases of gcc starting with 4.2, all the way to 4.4, but only on
platforms where va_arg is an array (e.g., x86_64 and POWER).

> Both gcc 4.3.0 and 4.3.1 choke on the [{{VA_LIST.cpp}}|http://svn.apache.org/repos/asf/stdcxx/branches/4.2.x/etc/config/src/VA_LIST.cpp]
config test. A misconfigured {{va_list}} can't be good for the library... We should probably
hardcode the expected value when {{\_RWSTD_NO_VA_LIST}} is #defined (although we might already
be doing it since we do have some good gcc 4.3.0 builds...)
> The ICE has been filed with gcc in [bug 37404|http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37404].
