liblto_plugin.so undefined symbol xasprintf

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

HI all,

Yesterday I upgrade source and rebuilt all distribution and installed 
it. I just started the process again to be sure, but it takes time!


However, now I cannot compile programs, linking fails. I get this issue:

ld: /usr/libexec/liblto_plugin.so: error loading plugin: 
/usr/libexec/liblto_plugin.so: Undefined PLT symbol "xasprintf" (symnum 
= 123)


Is something missing/dirty in my install? How can I fix that?

Thank you.

Riccardo
