Isn't this related to the glibc bug ? (bug 196207). Is it reproducible after setting the MALLOC_CHECK_ env var to "" ? Regards Calling free() on address 0x6 isn't a glibc bug :) Backtrace with MALLOC_CHECK_ set to 0: Application: Ark (ark), signal: Segmentation fault [Current thread is 1 (Thread 0xb51b6a80 (LWP 21840))] Thread 2 (Thread 0xb3234b70 (LWP 21864)): #0 0xffffe424 in __kernel_vsyscall () #1 0xb5cd9d95 in pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S:122 #2 0xb26e7db7 in QTWTF::TCMalloc_PageHeap::scavengerThread (this=0xb27bf1a0) at /local/git/Qt/qt/src/3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:2304 #3 0xb26e7e01 in QTWTF::TCMalloc_PageHeap::runScavengerThread (context=0xb27bf1a0) at /local/git/Qt/qt/src/3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:1438 #4 0xb5cd56e5 in start_thread (arg=0x0) at pthread_create.c:297 #5 0xb5cd5600 in ??
