ioc linux crash using errlogprintf

[haquin <haquin@ganil.fr>]

Hi all,

In my current dvp, for debug purpose, I use errlogPrintf (which I expect not to be intrusive like printf ...) and it 
crashes my Linux IOC.

I can reproduce the problem using an example application with just a sub record and putting the following loop in the 
process function :
    for (i=0; i<bugErrLogSubLoop; i++)
        errlogPrintf("[%ld]%s\n", i, "Dummy String Dummy String Dummy String Dummy String \0");

The sub record is periodically scanned every 10 sec.

I set the value of the "bugErrLogSubLoop" on IOC shell (var bugErrLogSubLoop 50),

when 10 < bugErrLogSubLoop < 50 errlog says messages were discarded
as soos as bugErrLogSubLoop >=50 the IOC crashes ! (segmentation error)

the problem does not occur on VxWorks, messages are only discarded but IOC never crash.

does anyone have the same pb ?
I gess that the lib used under VxWorks is different than the one with Linux, but what is this lib and what can I do ?

regards.
