Eek ! It looks to me like the data needs to go into the heap. RAII will help with tidyup. > Usual Linux stack is around 8MB, but e.g. on Windows I think just 2MB. Linux kernel has a script checkstack.pl. This might help. I will try an experimental build of gcc with -Wstack-usage=100000 and report back.
