double free detected in tcache 2 #10557
Description
Describe the bug
The following error message appears when Icinga cannot start due to config loading issues:
free(): double free detected in tcache 2
Caught SIGABRT.
To Reproduce
- Configure Icinga to load config files from a directory:
include "features-enabled/*.conf"
- Remove the directly read permission, so Icinga can't find the
*.conffiles within - Start the service or run
icinga2 daemon -C
Icinga is going to crash:
critical/config: Error: Error while evaluating expression: Function call 'glob' for file '/etc/icinga2/features-enabled/*.conf' failed with error code 13, 'Permission denied'
Location: in /etc/icinga2/icinga2.conf: 50:1-50:33
/etc/icinga2/icinga2.conf(48): * the features-enabled directory.
/etc/icinga2/icinga2.conf(49): */
/etc/icinga2/icinga2.conf(50): include "features-enabled/*.conf"
