What did you expect to see? I expected the "race.bash" to run without any errors or issues. What did you see instead? The stack trace of the error is as below: fatal error: stack growth after fork runtime stack: runtime.throw({0x12967aa, 0x17}) /home/vishwa/Workspaces/golang/go...
The de-facto rule for 1.4 is: you can pass any Go pointer to C. C code may use it freely. If C code stores the Go pointer in C memory then there must be a live copy of the pointer in Go as well. You can allocate Go memory in C code by calling the Go function_cgo_allocate....
The first field in the struct points to the code of the function, which will be equivalent to a pointer to a C function whose parameter types are equivalent, with an additional trailing parameter. The trailing parameter is the closure, and the argument to pass is a pointer to the Go ...
