Hi again. Interesting, gcc-4.1.2 seems to discover initialization problems even across function calls, triggering another -Werror failure in build of binutils-2.17:
In file binutils/wrstabs.c the initialization is lacking in stab_tag_type(), and the compiler tells us this, but points out line 1297 which is in a different function, where size can be used uninitialized (in the form of *psize) If I initialize size with 0 in stab_tag_type(), building continues. I assume that this is what would happen anyway if the warning was not detected. Still, I don't know if there also, a real problem could be triggered depending on input...?
