*Synopsis*: ksh93 mishandles GNU ld genscripts.sh script
Product: solaris
Category: shell
Subcategory: korn93
Type: Defect
Subtype:
Status: 3-Accepted
Substatus:
Priority: 2-High

Keywords: gnu-ld, opensolaris
=== *Description* ============================================================
Category
shell
Sub-Category
korn93
Description
When trying to build GNU ld from the GNU binutils CVS repository on
a self-built
snv_147, the ld/genscripts.sh failed, which doesn't happen with the
former
/bin/sh (i.e. /usr/has/bin/sh).
Frequency
Always
Regression
solaris_10
Steps to Reproduce
Consider the following script:
% cat genscripts.sh
#!/bin/sh
TMP=tmp
(
. source.sh
) | cat > out
rm -f ${TMP}
% cat source.sh
eval "cat > $TMP" <<EOF
EOF
sed -e '1d' $TMP
sed -e '2d' $TMP
% chmod +x genscripts.sh
% ./genscripts.sh
% sed: can't read tmp: No such file or directory
Expected Result
The scripts runs without errors, as it does with both
/usr/has/bin/sh and bash.
Actual Result
The script errors out as above, obviously removing ${TMP} too early
Unfortunately, the error vanishes if running genscripts.sh with sh -x,
unlike
the full genscripts.sh from
http://sourceware.org/cgi-bin/cvsweb.cgi/src/ld/genscripts.sh?rev=1.31&content-type=text/x-cvsweb-markup&cvsroot=src
where the early removal can clearly be seen when running with sh -x.
