26653 external/tcmalloc+/tcmalloc/internal/system_allocator.h:585] MmapAligned() failed - unable to allocate with tag (hint=0x4e9e40000000, size=1073741824, alignment=1073741824) - is something limiting address placement?

26653 external/tcmalloc+/tcmalloc/internal/system_allocator.h:592] Note: the allocation may have failed because TCMalloc assumes a 48-bit virtual address space size; you may need to rebuild TCMalloc with TCMALLOC_ADDRESS_BITS defined to your system’s virtual address space size

26653 external/tcmalloc+/tcmalloc/arena.cc:59] CHECK in Alloc: FATAL ERROR: Out of memory trying to allocate internal tcmalloc data (bytes=131072, object-size=16384); is something preventing mmap from succeeding (sandbox, VSS limitations)?

How to fix it? Thank you

Please check the system requirements.

Thank you for the response, my system should able to run it. The origin of the error is not from Mojo, but Tcmalloc. I encountered exact same error message from Tcmalloc in another project in the past. It seems that Tcmalloc is not portable, is there a way to change it to a more portable allocator like Mimalloc?
