Description

Now __builtin_setjmp/__builtin_longjmp are used with x64-mingw.

ruby 2.2.0dev (2014-04-07 trunk 45529) [x64-mingw32]
gcc version 4.8.2 20130712 (prerelease) (Built by MinGW-builds project)

.ext/include/x64-mingw32/ruby/config.h

#define RUBY_SETJMP(env) __builtin_setjmp((env))
#define RUBY_LONGJMP(env,val) __builtin_longjmp((env),val)

But this casues SEGV with callcc.

ruby -rcontinuation -e "callcc{|c|c.call}"

Instead using setjmpex/longjmp seems to work fine.

#define RUBY_SETJMP(env) setjmpex((env))
#define RUBY_LONGJMP(env,val) longjmp((env),val)

configure.in: no __builtin_setjmp on x64-mingw

  • configure.in: get rid of builtin_setjmp/builtin_longjmp on x64-mingw, which causes SEGV with callcc. [ruby-core:61887] [Bug #9710]
