Hi Simon, thanks for your quick reply. 1) ... so you can reproduce this? 2) Do you know a way how this can be 'foreseen'? We allocate larger matrices in the copula package depending on the user's input dimension. It would be good to tell her/him "Your dimension is quite large. Be aware of killers in your neighborhood"... before the killer attacks. Thanks & cheers,

...he blue. Since that decision is made by the kernel and it doesn't expose its thinking about how it feels, it's hard to tell. I couldn't find any API on OS X akin to didReceiveMemoryWarning in iOS, unfortunately. You could guess - e.g. by checking the total system memory int mib [] = { CTL_HW, HW_MEMSIZE }; int64_t value = 0; size_t length = sizeof(value); sysctl(mib, 2, &value, &length, NULL, 0); and comparing it to the sizes involved. However, even that is not foolproof, because it all depends on the other processes' memory usage, swap space size etc. There are slightly m...

I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to get it. Here's what I have: -a new file, lpc_asm.s, which has the assembly routines -changes to cpu.h, cpu.c, and stream_decoder.c to enable them -changes to configure.in to support the new cpu stuff -a preliminary Makefile.am -maybe something else I'm forgetting Now automake complains that configure.in
