Note that heap profiling is even more a black art than time profiling; you may need to do a lot of experimentation to find an enlightening profile.

Black art indeed... I did -hc, looked at the postscript generated from every angle I could and it looks like this: /| /| /| / | / | / | / | / | / | / | / | / | / |/ |/ | This is only xparse, other functions are unimportant and aren't even visible on the graph. My xparse allocates a lot of memory which is then almost all freed at the very next occasion by GC. Seems I do not have space leaks. The problem is that my prog allocates a lot just to free it immediatelly after. But what? -- Gracjan
