When C++ support is enabled, configure unconditionally probes `-lstdc++` and keeps it in LIBS if the link test succeeds. On platforms using libc++, this probe can succeed at compile time (if libstdc++ headers/libraries happen to be installed) but then cause runtime failures when configure tries to execute test binaries because `libstdc++.so.6` isn't actually available. Add a `--with-cxx-stdlib=<libstdc++|libcxx>` option that lets the build system specify which C++ standard library to link. When given, the probe is skipped and the specified library is linked directly. When not given, the original probe behavior is preserved. |

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: https://jemalloc.net/
