Package: cmake
Severity: important
By default ctest -T MemCheck runs:
35: MemCheck command: /usr/bin/valgrind "-q" "--tool=memcheck"
"--leak-check=yes" "--show-reachable=yes" "--workaround-gcc296-bugs=yes"
"--num-callers=50"
However as per documentation:
When enabled, assume that reads and writes some small distance below the stack
pointer are due to bugs in GCC 2.96, and does not report them.
The "small distance" is 256 bytes by default. Note that GCC 2.96 is the default
compiler on some ancient Linux distributions (RedHat 7.X) and
so you may need to use this option. Do not use it if you do not have to, as it
can cause real errors to be overlooked. A better alternative is
to use a more recent GCC in which this bug is fixed.
Since GCC 2.96 never entered debian, I would really like to see this option
removed.
Thanks
