 Hello Wolfgang,
 
     I've found that test case. In fact, it is not a specially written 
 test case, it is just a piece of preprocessed C++ code, very heavy on 
 templates. It has been manually reduced, eliminating a lot of unrelated 
 #includes, types, classes and member functions. What remains is about 
 25Kb file which contains several class templates and _one_ function that 
 takes one parameter of type "pointer to some complicated template class" 
 and has an empty function body. If I would have commented out this 
 function, the file would compile perfectly producing an empty .o file. 
 (I mean an object file with no one function in it, not a zero-sized 
 file). However, it doesn't look like the problem is in this particular 
 function. This function acts merely like a trigger, causing all of the 
 above templates to be instantiated at once. And it looks asif something 
 goes wrong during template instantiation (or generating dwarf debug info 
 for all these instantiated templates). Well... it's just my speculations...
     How do I send this file to you, then? You've told me not to send 
 attachments, and 1000 lines of code is too much to send in a mail body. 
 I can put its gzipped version somewhere to http, so you can download it. 
 Or upload it to your ftp.
 
 Cheers,
 Igor
