New issue 339 by [email protected]: ASAN and interaction with GNU
Smalltalk JIT
https://code.google.com/p/address-sanitizer/issues/detail?id=339
What steps will reproduce the problem?
1. From the C-stack we call into a "trampoline" that will take the first
argument and jump to the address that was passed.
2. When the first C method is being called that is using a stack variable
there will be stack-overflow
I would like to know if this is a known problem and what the JIT should do
to indicate the new start of the C-stack?
The runtime code is here:

And a call from the JIT to C code can be seen here:
http://git.savannah.gnu.org/gitweb/?p=smalltalk.git;a=blob;f=libgst/xlat.c;h=47978ac156a56f537885679f1c590a9d516c008a;hb=HEAD#l2964
