Above is a helgrind error I get on my AMD64 system. http://etbe.coker.com.au/2009/06/22/valgrindhelgrind-and-stl-string/ Below is a patch I wrote which appears to solve this problem. According to the comments on my above blog post it seems possible that this patch will also slightly improve performance on SMP systems when under heavy load. --- ../t/openssl-0.9.8g/crypto/mem.c 2003-12-01 23:06:15.000000000 +1100 +++ crypto/mem.c 2009-06-25 10:42:03.000000000 +1000 @@ -254,10 +254,12 @@ if (num <= 0) return NULL; - allow_customize = 0; + if(allow_customize) + allow_customize = 0; if (malloc_debug_func != NULL) { - allow_customize_debug = 0; + if(allow_customize_debug) + allow_customize_debug = 0; malloc_debug_func(NULL, num, file, line, 0); } ret = malloc_locked_ex_func(num,file,line); @@ -295,10 +297,12 @@ if (num <= 0) return NULL; - allow_customize = 0; + if(allow_customize) + allow_customize = 0; if (malloc_debug_func != NULL) { - allow_customize_debug = 0; + if(allow_customize_debug) + allow_customize_debug = 0; malloc_debug_func(NULL, num, file, line, 0); } ret = malloc_ex_func(num,file,line); -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
