Crash observed during counter update

[sdollp]

Hi,

I have a infinite loop in main thread with a sleep timer of 5 sec. It updates Prometheus counters every time. I am seeing segmentation fault when thread tries to aquire write lock in prom_counter_add () function.

Below is stack trace.

(gdb) bt
#0 0x00007f35c20f91b6 in pthread_rwlock_wrlock () from /lib64/libpthread.so.0
#1 0x00007f35c25154e8 in prom_metric_sample_from_labels () from /lib64/libprom.so
#2 0x00007f35c2513431 in prom_counter_add () from /lib64/libprom.so

#4 0x000000000040a761 in ran_adaptor_loop ()
#5 0x00000000004069df in main ()

Please suggest.
