#3745: Non-deterministic behavior with FFI
---------------------------------+------------------------------------------
Reporter: gchrupala | Owner:
Type: bug | Status: new
Priority: high | Milestone: 6.12.2
Component: Compiler (FFI) | Version: 6.10.4
Keywords: | Difficulty:
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: Incorrect result at runtime
---------------------------------+------------------------------------------
Comment(by simonmar):
I can't reproduce it here on my laptop (x86/Linux). Some questions:
* can you make it happen on more than one machine? what platform(s)?
* do you get different results when the program is compiled with
`-debug`?
* does valgrind say anything?
* does it happen with 6.12.1?
Is it possible there's a memory error in the FFI code, or the C++ code?
perhaps an off-by-one array size?
