it's easy to find out what the reason is. gcc has a very useful option
'--save-temps'. it instructs preprocessor, compiler and assembler to
leave their temporary files in place, so if you compiling, say, zzz.c,
you'll get zzz.i (output of preprocessor), zzz.s (assembly source --
output of compiler) and zzz.o (compiled binary object). You want to
look into zzz.i it shows what your source file turns into, and it's
almost always easy to see why.
