        Description

        New 64-bit Linux kernels have a default stack guard of a megabyte between the main stack and any allocated memory. 32-bit Linux x86 HotSpot allocates an executable memory region just beyond the end of the stack. When the stack grows to within a megabyte of this region the process segfaults and is killed.
