> That define is really only used for some statics code in > llallocator.cpp. It does > not influence if tcmalloc is used or not. its not clear where/why/when it is used - any code path includuing tcmalloc on linux 32bit isn't compiled, though the viewer crashes if it isn't linked, which in my opinion at least needs a comment *that* just linking it makes a difference. Even better would be a comment with e.g. a link to furher information about *why* just linking it makes a difference. For Linux 64bit not linking tcmalloc makes no difference (anything is aligned anyway, and I didn't see any difference in speed).
