Hi list,
nagios dumps core with SIGSEV on Solaris 10 when a plugin does not print=20
any output.
Using gdb I found it happening in line 803 of base/checks.c, where=20
checkresult_dbuf.buf is 0x0 on empty plugin output.
Versions:
- nagios-3.0.3 and nagios-cvs (as of 24. Sept 2008)
- Solaris 10 x86
- both Sun Studio 11 and gcc
I tried a fix just in place by inserting a NULL pointer check just before=20
the fprintf in line 803 ... maybe there is a more elegant solution.
=20
On linux, glibc seems to handel this problem in printf("output=3D%s", NULL)=
=20
by returning the string "(null)".
Regards,
Torsten
