syscall compare against a variable sv_minsigstksz in struct sysentvec as to properly take the size of the machine- and ABI dependent struct sigframe into account. The SVR4 and iBCS2 modules continue to have a minsigstksz of 8192 to preserve behavior. The real values (if different) are not known at this time. Other ABI modules use the real values. The native MINSIGSTKSZ is now defined as follows: Arch MINSIGSTKSZ ---- ----------- alpha 4096 i386 2048 ia64 12288 Reviewed by: mjacob Suggested by: bde
