Depending on the compilation flags the same ice will trigger at different
times, but I know which code line causes this, however I have not been
successful at reducing the bug. Possibly with smaller source, the bug won't
show up.
The bug seems to be triggered in class filename_pool which is at line 57241 in
the preprocessed source. In a reduced testcase the compilation simply fails
with an undefined reference to intrusive_ptr_release(filename_pool::holder*).
The line 'friend void intrusive_ptr_release(holder*);' after the nested struct
holder{}; must be moved above the declaration of holder together with a forward
declaration of holder to be able to compile again.
compilation flags: -save-temps -g -Wall
