Fixed upstream with https://github.com/AcademySoftwareFoundation/openvdb/commit/0fa1c68314dfac1822711f5775976ce0735e041e
** Description changed: - See here : https://github.com/AcademySoftwareFoundation/openvdb/issues/732 - It seems the issue is due to jemalloc. - Using openvdb7.0 the problem dispears, probably thanks to the following: + [Impact] - * d/control: Remove dependency to jemalloc. See #951704 for details + * This issue causes apps to be unable to dlopen libopenvdb6.2 or any + shared libraries that depend directly or indirectly on libopenvdb6.2. + Notably this includes libopenimageio2.1 and anything that depends on it. + The python3-openvdb package also doesn't work in focal at present + because of this issue. - Would it be possible to remove the dependency to jemalloc on the focal - version (6.2) or backport version 7.0 from groovy to focal ? + * This issue is a good candidate for backporting to focal because (1) + the fix is a very modest change to the build of the libopenvdb6.2 + package; (2) this is a regression from the previous stable release of + Ubuntu (bionic); (3) several packages are affected by it. + + * The change already in groovy fixes this issue by not building + libopenvdb with jemalloc. + + [Test Case] + + * `apt install python3-openvdb && python3 -c "import pyopenvdb"` should + succeed, but because of this issue it currently fails with the error + "cannot allocate memory in static TLS block". + + * Also, the following C program should print a non-nil value to stdout: + + ```c + #include <dlfcn.h> + #include <stdio.h> + + void main() { + printf("%p\n", dlopen("/usr/lib/x86_64-linux-gnu/libopenvdb.so.6.2", RTLD_NOW)); + } + ``` + + [Regression Potential] + + * Regressions are unlikely because the only change is to the choice of + allocator for libopenvdb6.2 when configuring the build with CMake. + + * There is no need for a patch to libopenvdb. + + * The patch applied in groovy is https://salsa.debian.org/multimedia- + team/openvdb/-/commit/ac393d95aa19d29c23a97dca1ace23061ebe5c17 + + [Other Info] + + * There are workarounds for this issue, but each has its own drawbacks + and may not be possible in every situation where this issue could occur. + + * Upstream issue + https://github.com/AcademySoftwareFoundation/openvdb/issues/732 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: libopenvdb-dev 6.2.1-8ubuntu1 ProcVersionSignature: Ubuntu 5.4.0-33.37-generic 5.4.34 Uname: Linux 5.4.0-33-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.2 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Wed Jun 10 19:49:55 2020 InstallationDate: Installed on 2020-05-15 (26 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) SourcePackage: openvdb UpgradeStatus: No upgrade log present (probably fresh install) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882998 Title: Cannot import openvdb 6.2 on Focal due to jemalloc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jemalloc/+bug/1882998/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
