--- Comment #16 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Andreas Schwab from comment #15) > TASK_SIZE is 0xF0000000UL on m68k. That would mean ~3.75GB virtual address space is available. The cited /proc/maps though looks like the lower half isn't available? It would be probably interesting to strace the process that will ultimatively run out of virtual memory to see how glibc places allocations. A simple test program repeatedly creating anonymous mmaps of a larger size (2MB?) might also get an upper bound.
