And avoid signal handler calling signal unsafe functions, and/or calling unlink with uninitialized memory pointer. 2020-02-19 Bernd Edlinger <bernd.edlinger@hotmail.de> * collect2.c (c_file, o_file): Make const again. (ldout,lderrout, dump_ld_file): Remove. (tool_cleanup): Avoid calling not signal-safe functions. (maybe_run_lto_and_relink): Avoid possible signal handler access to unintialzed memory (lto_o_files). (main): Avoid leaking temp files in $TMPDIR. Initialize c_file/o_file with concat, which avoids exposing uninitialized memory to signal handler, which calls unlink(!). Avoid calling maybe_unlink when the main function returns, since the atexit handler is already doing this. * collect2.h (dump_ld_file, ldout, lderrout): Remove.
