Description Xavi Hernandez 2020-02-11 13:22:47 UTC

Description of problem:

When a process calls glfs_fini(), some memory management structures are destroyed. However the process might not finish after that. In that case, a new call to glfs_init() won't fully reinitialize all structures for already running threads, which can lead to memory corruption and crashes.
