Dear all, With R.2.7.0 (on windows XP) I have encountered what seems to be a "negative memory size". If I use gc() afterwards the R goes down. I use R_alloc for *most* memory allocations in my C-routines:> memory.size()[1] 11.08132> dyn.load("rconipm.dll")....> dyn.unload("rconipm.dll") > memory.size()[1] -1012.854 Has anybody encountered similar problems? (It all worked well under R.2.6.2, but I am of course not blaming R for failing). Regards S?ren
