bug still exists in 5.9 - the tcsh package has been updated, as far as i can tell. bug does not seem to exist in the tcsh617 package. thanks, richard Old release of tcsh-6.14.00 does not support dynamically allocated buffers (available since tcsh-6.14.03) so buffers can easily overflow like in your example. This one issue is fixed in RHEL-6 therefore I am closing the bug as WONTFIX. |
Description of problem: in tcsh, it seems that if the output from eval `x` is greater than 333 lines, a segmentation fault occurs. Version-Release number of selected component (if applicable): tcsh-6.14-17 How reproducible: always Steps to Reproduce: % cat test.sh #!/bin/sh ECHO=/bin/echo for i in `seq 1 1000` do echo "$ECHO $i ;" done % eval `test.sh` | egrep '.*' 1 2 3 ... 332 333 Segmentation fault Actual results: segmentation fault Expected results: no error Additional info: also tested on a el6.2/x86_64 system, which returned no error.
