A.2.114 -xcheck[=i]
SPARC: Compiling with -xcheck=stkovf adds a runtime check for stack overflow of the main thread in a singly-threaded program as well as slave-thread stacks in a multithreaded program. If a stack overflow is detected, a SIGSEGV is generated. If your application needs to handle a SIGSEGV caused by a stack overflow differently than it handles other address-space violations, see sigaltstack(2).
