Comment (by Gary Buhrmaster):

 Replying to [comment:12 Klaas de Waal]:

 > 2. Thread-safety (or lack thereof)
 > The errors as reported by valgrind in file valgrind-19.10-master6.log
 show that the failing function, hdhomerun_sock_recv, is called from two
 different threads: Thread 37 Signal Monitor (see line 10876) and Thread 36
 Scanner (see line 15607).
 > Looking carefully at the valgrind messages following line 10876 it shows
 that the "invalid read" is done by the signal monitor; it is reading the
 value just free'd by the scanner.

 I have this recollection this (or something like it) was reported in a
 previous ticket, and SiliconDust indicated that you needed to create a new
 object for each thread...
