I suspect a bad cached compile from  gcc.
ccache calculates a hash based on the preprocessed input file, the compiler 
version and the compiler flags. If the hash matches, ccache uses the 
previously 
compiled output or error file.

what happen if you reenable ccache and choose some different CFLAGS, just for 
the bad file?  This should force a fresh compile, as ccache will not find a 
match.


Looking at the source file, their are no #ifdef which could cause problems.  
It 
is as if  gcc misread part of the file.
