How did that > argument get its value? I am fluent neither in C nor gdb. Does not "first=0xffffffff <Address 0xffffffff out of bounds>" answer the first question? I tried to go a little bit further by setting breakpoints at 'add_new_plugin' and 'default_plugin_dir_name' and tried to print 'plugindir_string', but ran out of idea at Breakpoint 3, default_plugin_dir_name () at ../../gcc-4.6-work/gcc/plugin.c:880 880 if (!plugindir_string) (gdb) p plugindir_string No symbol "plugindir_string" in current context.
