bug#20244: automake 1.15: tests-environment-fd-redirect hangs on RHEL 6.6, CentOS 6.6 w/ ksh 2012-08-01

[Diab Jerius]

When testing automake 1.15, the tests-environment-fd-redirect test
hangs on RHEL 6.6 and CentOS 6.6 when testing ksh.

The ksh that is installed on the RHEL system is:

% rpm -qi ksh

Summary     : The Original ATT Korn Shell
Description :
KSH-93 is the most recent version of the KornShell by David Korn of
AT&T Bell Laboratories.
KornShell is a shell programming language, which is upward compatible
with "sh" (the Bourne Shell).

(That on the CentOS system is equivalent)


To reproduce this behavior, unpack the automake tar ball in /tmp (so
the paths below make sense).

% ./configure

% make

% make check TESTS=t/tests-environment-fd-redirect
make  check-TESTS check-local
make[1]: Entering directory `/tmp/automake-1.15'
make[2]: Entering directory `/tmp/automake-1.15'

and it will hang.  To debug further, kill the build via ^C, and it
unfortunately deletes the log file:

^Cmake[2]: *** Deleting file `t/tests-environment-fd-redirect.log'
^Ctests-environment-fd-redirect: hard error: caught signal SIGINT
make[2]: *** [t/tests-environment-fd-redirect.log] Error 130
make[1]: *** [check-TESTS] Interrupt
make: *** [check-am] Interrupt

but, t/tests-environment-fd-redirect.dir will have been initialized.

So,

% cd t/tests-environment-fd-redirect.dir

% PATH='/tmp/automake-1.15/t/ax:'$PATH  /bin/ksh ./configure
CONFIG_SHELL=/bin/ksh
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether make supports nested variables... yes

and it hangs.


Thanks!
