** Description changed:
- When starting a Callgrind session using "valgrind", the actual
- executable name is "valgrind.bin". However, when callgrind_control
- searches for processes, its Perl regexp does not allow for this
- possibility. See callgrind_control line 32:
+ [Impact]
+ When starting a Callgrind session using "valgrind", the actual executable
name is "valgrind.bin". However, when callgrind_control searches for processes,
its Perl regexp does not allow for this possibility. See callgrind_control line
32:
+ Additionally the code contains several buffer overflows that can break
depending on compiler optimizations.
- if (/^use --pid=(\d+) for \S*?valgrind\s+(.*?)\s*$/) {
+ [TESTCASE]
+ $ valgrind --tool=callgrind sleep 100 &
+ $ callgrind_control -b
+ No active callgrind runs detected.
+ After making the change:
+ $ valgrind --tool
+ $ callgrind_control -b
+ PID 23522: sleep 100
- Callgrind_control works as expected again after changing this line to:
+ [Regression Potential]
+ the program currently doesn't work properly so there is little risk of things
getting worse.
+ The overflow fixes are applied upstream since several month and the process
name fix is also in debian wheezy.
- if (/^use --pid=(\d+) for \S*?valgrind(?:\.bin)?\s+(.*?)\s*$/) {
-
- Please make this change in your package (or upstream).
-
- Steps to reproduce:
- $ valgrind --tool=callgrind sleep 100 &
- $ callgrind_control -b
- No active callgrind runs detected.
- After making the change:
- $ valgrind --tool
- $ callgrind_control -b
- PID 23522: sleep 100
