Bug ID: 496552
Summary: intermittent false positives with JNI code?
Classification: Developer tools
Product: valgrind
Version: 3.23.0
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: jsew...@acm.org
Reporter: wallstp...@gmail.com
Target Milestone: ---
We regularly regression-test our code with valgrind, including some JNI code,
and those tests always pass at this point. Except yesterday, when we got a
bunch of "Illegal read/write" errors.
I've satisfied myself as best I can that these are false positives by examining
the source, but at the same time I don't recall ever seeing a true false
positive from valgrind before, so I'm suspicious of that explanation.
I know this is a long shot, but I've attached the report file and I'd be very
grateful if someone has the time to take a look and see if anything odd jumps
out. As you can see, we're running memcheck on the JVM, which generates a LOT
of output (we use the scripts from https://github.com/nyfix/memleaktest to pare
that down to something manageable).
The bits that are relevant to this discussion are at lines #9655-10497.
Any suggestions much appreciated -- thanks in advance!
