I tried gcc-4.2.2 and result is the same.
I also tried to push some 0xdeadbeef into the stack of calling ipc
(code of l4_ipc_call_tag into ipc-l42-gcc3-pic.h). When pf occurs, I
don't find the markers into the stack of X thread. Maybe stack is
corrupted or I don't understand what happens ?
Have you some hint, tips to understand what happens ?
