I have 1gb ECC memory. It is a brand new HP ML360 Server with 3GHz INTEL XEON processor, 73gb SCSI HDD. The system has a fresh os install...
Tried to sett it '-1' and ... nothing ... the same error ...
I don't think that it is relay a resource problem... Take a look at the memory size that it try to allocate : 4294967295 bytes = 3.99 Gb for a printing object ... it is waaaaaay to much...
Did that too .. nothing found .. I even posted on PHP's bugs web page ... they sent me to PECL's bugs web page .... and from them .. no answerer ...
