  "message": "gprofng: fix infinite recursion on calloc with multi-threaded applications\n\nlibcollector uses pthread_getspecific() and pthread_setspecific() to access\nthread local memory. libcollector uses this memory to check that\ninterposed functions (like malloc, calloc or free) don\u0027t have recursion.\nThe first time we call calloc(), we call pthread_setspecific() to create\na thread-specific value.\nOn Ubuntu machine, pthread_setspecific() calls calloc(), and we cannot intercept\nsuch recursion.\ngcc supports thread-local storage. For example,\n  static __thread int reentrance \u003d 0;\nI rewrote code using this instead of pthread_setspecific().\n\ngprofng/ChangeLog\n2024-03-23  Vladimir Mezentsev  \u003cvladimir.mezentsev@oracle.com\u003e\n\n\tPR gprofng/31460\n\t* libcollector/heaptrace.c: Use the __thread variable to check for\n\t* reentry. Clean up code.\n",
