With -buildmode=c-archive, initsig is called before the memory allocator has been initialized. The code was doing a memory allocation because of the call to funcPC(sigtramp). When escape analysis is fully implemented, that call should not allocate. For now, finesse the issue by calling a C function to get the C function pointer value of sigtramp. When returning from a call from C to a Go function, a deferred function is run to go back to syscall mode. When the call occurs on a non-Go thread, that call sets g to nil, making it impossible to add the _defer struct back to the pool. Just drop it and let the garbage collector clean it up.

VERSION |
See ../README. This is the runtime support library for the Go programming language. This library is intended for use with the Go frontend. This library should not be stripped when it is installed. Go code relies on being able to look up file/line information, which comes from the debugging info using the libbacktrace library. The library has only been tested on GNU/Linux using glibc, and on Solaris. It should not be difficult to port to other operating systems. Directories: go A copy of the Go library from http://golang.org/, with several changes for gccgo. runtime Runtime functions, written in C, which are called directly by the compiler or by the library.
