Antoine Pitrou commented on ARROW-3979:
---------------------------------------
If you need guidance or help on this don't hesitate to ask.
One issue I've noticed is with the re2 library. I've added this to the
{{valgrind.supp}} file:
{code:java}
# Various issues in the re2 regexp constructor (used by Gandiva)
{
<re2>:Conditional jump or move depends on uninitialised value(s)
Memcheck:Cond
...
fun:_ZN3re23RE2C1E*
}
{
<re2>:Use of uninitialised value of size 8
Memcheck:Value8
...
fun:_ZN3re23RE2C1E*
}
{code}
Another issue is the following macro:
{code:java}
#define REGISTER_EXPORTED_FUNCS(classname) \
static bool _registered_##classname = ExportedFuncsRegistry::Register(new
classname)
{code}
It allocates an object that's never deleted. One solution is to use a
{{unique_ptr}} or {{shared_ptr}} instead. If not possible, then it should be
silenced in the suppressions file.
