It has been rebuilt a number of times recently. Last night's test run still shows the bug and it used: dave@gsyprf11:~/gcc-4.6/objdir$ ld --version GNU ld (GNU Binutils) 2.21.51.20110116 I tried to do a build without plugin support, but it seems there is a ld configure bug and plugin support can't be disabled. With older versions, I think plugin support had to be explicitly enabled (default was no). I'll try to debug the lto_symtab contents tonight. Dave
