Maybe some files (stdlib.h or malloc.h) return no data when read?
Then, gcc still
"compiles" them, but all the declarations are missing. And I would expect gcc
to complain if zero blocks returned, and truncated files are very likely to
abort compilation.

Can the command be strace'd immediately after the failure?
