Indeed. Note that I was also able to reproduce the problem with "-g 
-02". So far, the CFLAGS="-g" was unable to crash the program even with 
the same setup (generating the base, crash, recompiling with "-g", no 
crash).

As for the flex scanner modifications, my question was about where we 
look for function calls. It seems we look for them in the database in 
"function-typed" tags whereas we could look for them within 
"global-symbols" tags.
The corresponding function is findcalledby() in find.c. We could add a 
case GLOBALDEF to the search function. This would remove the need to 
tweak the C function declaration pattern/regexp.

What do you think about that?

Vincent
