![]() The ARM ABI requires that the stack be aligned to 8 bytes as it is noted in Procedure Call Standard for the ARM Architecture: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042d/index.html Unaligned SP also causes the problem with variable-length arrays allocation when VLA address becomes less than stack pointer during aligning of this address, so the next 'push' in the stack overwrites first 4 bytes of VLA.
