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
