1974 | * We used to fclose(debug_log) here if it was set, but then | |
1975 | * we forgot to set it to NULL. That caused some coredumps | |
1976 | * because exit() ends up calling a bunch of destructors and | |
1977 | * such. So rather than forcing the debug_log to close, we'll | |
1978 | * leave it open so that those destructors can write some | |
1979 | * debugging if necessary. The file will be closed anyway when | |
1980 | * the process truly exits. | |
