Ruby Forum Ruby-core > Defect for the signal usage of SIGVTALRM in Ruby 1.9 implementation

Hi All

Given below are the defect descriptions for the signal usage of 
SIGVTALRM in
Ruby 1.9 implementation.

Defect Description:
In file trunk/thread_pthread.c, at line no: 153
In the "Init_native_thread" function, posix_signal function is called 
with
SIGVTALRM value setting an empty function as signal handler. The
"Init_native_thread" function is indirectly called from ruby_init(). As 
per
our understanding, SIGVTALRM is no longer a reserved signal in Ruby
1.9implementation and therefore no signal handler should be installed
for it.

1.9 still uses SIGVTALRM for context switching.
