Created an attachment (id=18927)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18927&action=view)
a small program which generates many files to exhibit the bug

The attached main.c file generates many files.

Put it in a new directory (empty).

Compile it with 
   gcc -O main.c -o main

Run it to generate many files, for example
  ./main 4000

it should display messages ending with

generated function #3904 in E_150
generated function #3968 in Q_152
generated 4000 files last is W_153.c
try to compile all 4000 files with:
         gcc-trunk -flto -O2 -DGENERATEDALL main.c [A-Z]*.c -o big


Now, run the suggest command (replacing gcc-trunk with what is appropriate for
you).

Regards.
