Package: dash
Version: 0.5.4-9
Severity: normal
I ran the cl-launch integrated test suite, a shell script that may be
overstressing the string allocation in dash, and got the error:
*** glibc detected *** dash: free(): invalid pointer: 0x0805d740 ***
I don't know what causes this, and it's not 100% reproducible, as some
runs of my test suite exhibit the bug (at different stages of the test),
and some do not. In any case, dash seems to be doing a double free or
something.
To maybe reproduce the bug, you can get cl-launch_2.09.sh as well as a
few common lisp implementations, and run the test suite in a temporary
directory then dash may eventually bork after a few hundreds of tests.
mkdir /tmp/foo
cd /tmp/foo
wget http://fare.tunes.org/files/cl-launch/cl-launch_2.09.sh
apt-get install clisp gcl gclcvs cmucl sbcl
./cl-launch_2.09.sh -l 'clisp cmucl gcl gclcvs sbcl' -B eval
'TEST_SHELLS="dash" ; tests'
I get the following failure:
../cl-launch_2.09.sh -l 'gcl gclcvs clisp cmucl sbcl' -B eval
'TEST_SHELLS="dash" ; tests'
Using test shell dash
cl-launch --lisp gcl --no-include --init ... --execute -- ...
success with test 00 :-)
cl-launch --lisp gcl --no-include --init ... --output ... ; out.sh ...
success with test 01 :-)
....
cl-launch --lisp clisp --include ... --file ... --init ... --output ... ;
out.sh ...
success with test 253 :-)
cl-launch --lisp clisp --update ... --include ... --file ... --init ...
--execute -- ...

Hello,
I am closing this bug because it does not seem to be reproducible with
the current version of dash. Feel free to reopen if you can still
reproduce it.
