[chuck-dev] gain ugen segmentation fault

[Ge Wang]

Hi Matt!

the -O specifies optimization level for gcc (0 is off, 1 is some, 3 is 
a lot).

if you like, try make clean and compile with -O2 and -O1 and see if the
crash is there.  it is possible that the optimization in your version 
of gcc
contains a bug that caused the crash.

Best,
Ge!
