Public bug reported:
libhwloc from hwloc-2.7.0-2 has a bug in which putenv() is used on a
static string in a library constructor. This can cause a segv in an
unrelated application if the application tries to modify the
environment, or if in this case libhwloc.so is unloaded by the dynamic
linker.
There is already a fix upstream which went into hwloc 2.7.1, which uses
setenv(3) instead of putenv(3). Can this fix be backported to the
package in Ubuntu 22.04?
