Bug #1342: signal handling on HP-UX
http://redmine.ruby-lang.org/issues/1342

Author: Graham Agnew
Status: Feedback
Priority: Low
Assignee: Yui NARUSE
Category: core
Target version: 1.9.x
ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [ia64-hpux11.23]


=begin
 Whenever I interrupt ruby on HP-UX 11i v2, I get a message from the operating system about an inability to establish context and a core dump.  This is the messages:
 
 > 
 > sendsig: useracc failed. 0x9fffffffbf7dae00 0x00000000005000
 > 
 > Pid 3044 was killed due to failure in writing the signal context - possible stack overflow.
 > Illegal instruction
 > 
 
 Looking at the stack backtrace in the core file shows the following:
 
 HP gdb 5.4.0 for HP Itanium (32 or 64 bit) and target HP-UX 11.2x.
