GCC10 -fanalyzer found a double fclose in asm_end. asm_end can call
text_end, which calls fclose and checks for errors, then asm_end
calls __libasm_finictx which can call fclose again (but doesn't
check for errors). Call fflush in text_end instead. fflush will
generate the same error fclose would i
GCC10 -fanalyzer found a possibly-NULL dereference after a failed
malloc in __libdw_alloc_tail. In this case we should call the Dwarf
oom_handler as is done in other places where an essential malloc
call fails. The oom_handler cannot return and will likely just abort.

GCC10 -fanalyzer found a double free when openstream failed. When
openstream fails __libdw_gunzip will call fail, which frees the
state->buffer. But openstream can call zlib_fail, which will also
call fail. Instead of calling zlib_fail, just return the error
that zlib_fail would have returned.
