Valgrind crashes in Qt Creator, related to video card?

I am using a Core i7 PC with NVIDIA GM107 GeForce GTX 750 Ti video card running Linux Mint 18.3. "Valgrind Memory Analyzer" crashes when running a blank "Qt Widgets Application" project in Qt Creator 4.10.1 with the "external error" message: 286,959 bytes in 1 blocks are possibly lost in loss record 78 of 78 in calloc in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so 1: calloc in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so 2: /usr/lib/nvidia-384/libGL.so.384.130 3: /usr/lib/nvidia-384/libnvidia-glcore.so.384.130 4: /usr/lib/nvidia-384/libnvidia-glcore.so.384.130 5: /usr/lib/nvidia-384/libGL.so.384.130 6: /usr/lib/nvidia-384/libGL.so.384.130 7: /usr/lib/nvidia-384/libGL.so.384.130 8: call_init.part.0 in /build/glibc-LK5gWL/glibc-2.23/elf/dl-init.c:58 9: call_init in /build/glibc-LK5gWL/glibc-2.23/elf/dl-init.c:30 10: _dl_init in /build/glibc-LK5gWL/glibc-2.23/elf/dl-init.c:120 11: /lib/x86_64-linux-gnu/ld-2.23.so Here's the run log: 19:17:40: valgrind --child-silent-after-fork=yes --xml- socket=127.0.0.1:41595 --log-socket=127.0.0.1:37293 --xml=yes --smc- check=stack --tool=memcheck --gen-suppressions=all --track-origins=yes --leak-check=summary --num-callers=25 /home/daniel/Documents/QtNew/build- TestWidgets-Desktop_Qt_5_12_5_GCC_64bit-Debug/TestWidgets 19:17:44: The program has unexpectedly finished. 19:17:44: Process exited with return value Process crashed 19:17:44: Analyzing finished. I don't get any warning / error if I run the program normally i.e. without Valgrind. **Update** I upgraded Valgrind from source to version "3.15.0" and the crash problem went away.
