--- Comment #8 from tmpsan...@tmpsantos.com.br ---
I just built r15831 and got the same crash when I hit libcurl + ssl. When I
comment the network code, valgrind works just fine.

vex: the `impossible' happened:
   isZeroU
vex storage: T total 4426865440 bytes allocated
vex storage: P total 640 bytes allocated

valgrind: the 'impossible' happened:
   LibVEX called failure_exit().
