Can you explain this more -- what exactly are trying to do? Are you trying

ok, debugging the compiler is not the typical user mode of use.
Do any of the following work for you?
*) don't use -frandom-seed (you don't say why you're using this flag)
*) copy and restore the coverage data file
*) stub out the unlink code at the end of coverage.c. (I presume that you're
rebuilding cc1 with optimization off anyway, and as you're debugging a compiler
problem with FDO you're somewhat familiar with coverage.c).
