Re: Problem with PostgreSQL 9.2.7 and make check on AIX 7.1

Hello,
This is the error description for the AIX 7.1 TL3 SP1/SP2 bug:

This bug is fixed in AIX 7.1 TL3 SP3.

IV56118: AT 7.1 TL 3, CALLING LONGJMP CAUSES SIGINT TO
         BE BLOCKED APPLIES TO AIX 7100-03 14/06/02 PTF PECHANGE

APAR status

  Closed as program error.

Error description

  If a program calls setjmp/longjmp, it will not be possible to
  use Ctl-C to exit the program any more, since SIGINT will be blocked.

Local fix

  Using _setjmp and _longjmp can avoid the issue.
