This fails:
./arch/sol11.i386\-64/bin/ksh -c 'x=$( /bin/true ; true ; )''
./arch/sol11.i386-64/bin/ksh: open file limit exceeded [Bad file number]
This does not fail:
./arch/sol11.i386\-64/bin/ksh -c 'x=${ /bin/true ; true ; }''
truss reports some suspicious syscalls:
fcntl(1, 4294967197, 0x0000000A) Err#22 EINVAL
fcntl(4294967295, F_SETFD, 0x00000001) Err#9 EBADF
close(1) = 0
My guess is that the new emulation for F_DUPFD_CLOEXEC is not
intercepted properly.
OS is Opensolaris 2011.05 (an early version of Solaris 11), which
didn't have F_DUPFD_CLOEXEC
