Hi Andrew: Here is some more valgrind evidence. valgrind gives relatively clean results for at least two of the noninteractive devices (epsqt and svgqt and probably all the rest of them as well, although I didn't check). For example, wine@raven> valgrind examples/c/x01c -dev svgqt -o test.svg ==18567== Memcheck, a memory error detector ==18567== Copyright (C) 2002-2011, and GNU GPL'd, by Julian Seward et al. ==18567== Using Valgrind-3.7.0 and LibVEX; rerun with -h for copyright info ==18567== Command: examples/c/x01c -dev svgqt -o test.svg ==18567== PLplot library version: 5.10.0 *** PLPLOT WARNING *** All pages after the first skipped because family file output not specified. ==18567== ==18567== HEAP SUMMARY: ==18567== in use at exit: 174,122 bytes in 1,880 blocks ==18567== total heap usage: 338,871 allocs, 336,991 frees, 32,709,897 bytes allocated ==18567== ==18567== LEAK SUMMARY: ==18567== definitely lost: 452 bytes in 9 blocks ==18567== indirectly lost: 61,414 bytes in 1,342 blocks ==18567== possibly lost: 4,676 bytes in 83 blocks ==18567== still reachable: 107,580 bytes in 446 blocks ==18567== suppressed: 0 bytes in 0 blocks ==18567== Rerun with --leak-check=full to see details of leaked memory ==18567== ==18567== For counts of detected and suppressed errors, rerun with: -v ==18567== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 10 from 6) So the memory management issue appears to be specific to interactive use, e.g., the qtwidget device and qt_example. So this supports the working hypothesis of nothing wrong with the Qt5 epa_build, but instead some issue for the underlying Debian stable system libraries that are used for the interactive case. I immediately thought of X in this context since my prior valgrind results were done with a thin client rather than direct display. So I repeated the qtwidget tests using a direct display with the following interesting result: wine@raven> valgrind examples/c/x01c -dev qtwidget ==18788== Memcheck, a memory error detector ==18788== Copyright (C) 2002-2011, and GNU GPL'd, by Julian Seward et al. ==18788== Using Valgrind-3.7.0 and LibVEX; rerun with -h for copyright info ==18788== Command: examples/c/x01c -dev qtwidget ==18788== PLplot library version: 5.10.0 ==18788== Syscall param ioctl(generic) points to uninitialised byte(s) ==18788== at 0x5406EB7: ioctl (syscall-template.S:82) ==18788== by 0xCBC6D07: drmIoctl (in /usr/lib/x86_64-linux-gnu/libdrm.so.2.4.0) ==18788== by 0xCBC913B: drmCommandWriteRead (in /usr/lib/x86_64-linux-gnu/libdrm.so.2.4.0) ==18788== by 0x122E5973: ???

values come from ==18788== ERROR SUMMARY: 26 errors from 22 contexts (suppressed: 17 from 7) So the direct display result apparently shows more details about what appears to be a drm memory management issue with thread confusion, and also note the wrong sysid of 18792 above for the complaints about invalid file descriptor (that wrong sysid also occurred for the thin client result). But ultimately, the direct display result also shows the invalid read caused by exiting PLplot just like the thin client result. So these results are still consistent with the working hypothesis (something wrong with Qt5's use of the system libraries for Debian stable but not other more modern platforms), and I look forward to your further tests of that working hypothesis.
