The function "fprintf()" does not belong to the list of async-signal-safe
functions.
See section "2.4.3 Signal Actions" from the document "2.4 Signal Concepts".

I guess that a different program design will be needed for your function
"do_sigsegv".

I recommend to change the data type for the variable "watchdog" to
"sig_atomic_t".
