exe: premature return when using --environment

[simonmeggle]

When compiled as exe, check_logfiles returns prematurely when using --environment on the Windows commandline. Tested with version 3.9 on different Windows machines (7/8/10, 64bit)

Test scenario

logfile with 200k lines.

minimalistic cfg file:

@searches = ({
  logfile => 'alllogs.txt',
  type	=> "virtual", 
  warningpatterns => '.*',
});

OK without environment

C:\cl_exe_test>check_logfiles_neu.exe -f cl_exe_test.cfg [enter]
[~8s execution time]
WARNING - (199129 warnings) - _(null)_ ...|'default_lines'=199129 'default_warnings'=199129 'default_criticals'=0 'default_unknowns'=0
C:\cl_exe_test>

NOK with environment

C:\cl_exe_test>check_logfiles_neu.exe -f cl_exe_test.cfg --environment WEBMODULE=foo [enter]
[~1s execution time]
C:\cl_exe_test>[enter]
C:\cl_exe_test>[enter][enter][enter][enter][enter][enter]....[enter][enter][enter][enter]
C:\cl_exe_test>WARNING - (199129 warnings) - _(null)_ ...|'default_lines'=199129 'default_warnings'=199129 'defaul
t_criticals'=0 'default_unknowns'=0
C:\cl_exe_test>

summary

As a result, when called by NSclient, check_logfiles services do not contain a service output.

workaround

Replacing environment variables with macros worked for my requirement.
