Description H.J. Lu 2007-07-02 22:36:18 UTC 
Gcc 4.3 revision 126234 needs more than 6GB to compile
27_io/basic_stringbuf/setbuf/wchar_t/4.cc in libstdc++.
It happens on Linux/ia32, Linux/ia64 and Linux/x86-64.
Revision 126166 is OK.
Comment 1 Paolo Carlini 2007-07-02 23:37:46 UTC 
I can confirm this. And .../setbuf/char/4.cc is almost as bad.

Comment 3 Richard Biener 2007-07-03 14:15:19 UTC 
Fixed with r126252.
