Martin Sebor updated STDCXX-856:
--------------------------------

    Affects Version/s:     (was: trunk)
                       4.2.0

Same problem in 4.2.0 so this is not a regression.

> [Sun C++] data corruption in rw_printf() with "%{$VAR!:@}", "%A{*c}", and "%{@}"

> When compiled with Sun C++ (both 5.9 and 5.8) in 15S build mode the program below exits with {{SIGABRT}}. It runs fine when compiled with HP aCC 3.73 or gcc 4.1.1 on Linux/x86_64 (both in wide mode). I suspect it might have something to do with STDCXX-828.
