I forgot to add the version of valgrind. The version is r15654.
The stable release also shows the same issue
Thanks

Subject: symbol look up error in helgrind
Hello,
When running my program in helgrind it dies after printing the following error on screen
==25217== Warning: client switching stacks? SP change: 0xffefff318 --> 0x2ec302fc21b27bd
==25217== to suppress, use: --max-stackframe=210596195555030181 or greater
==25217==

==25217== at 0x2EC302AC21B4ABF: ???
==25217==
Running in gdb the stack trace before the crash is

There are other pthread_XXX functions before the call in question and they have no issues. Only pthread_mutex_init seems to have a problem. The problem is repeatable. Any explanation on what is going and how to address it is very much appreciated. I'm willing to try any experimental code to get more information or try a fix
Thank you
