Error while parsing trace configuration with 2 sections

[Noremos]

I have the following configuration in fbtrace.conf:

database = /var/primary-db.fdb  
{  
  enabled = true  
  log_errors = true  
}  

database = /var/secondary.fdb  
{  
  enabled = true  
  log_connections = true  
}  

database  
{  
  enabled = true  
}  

It works fine when connecting to primary-db.fdb. However, the error appears when connecting to secondary.fdb or any other database.

  Trace plugin fbtrace returned error on call trace_create.
  error while parsing trace configuration
  line 1: error while compiling regular expression "/tmp/primary-db.fdb"

The Firebird configuration:
AuditTraceConfigFile = fbtrace.conf

I think this is unclear behavior because the trace works all the time but suddenly stops working when connecting to another database.

I suggest a possible solution: #8427
