Comment (by anonymous):

 In fact, throw/catch within a coroutine work with mingw32
 (libgcc_s_dw2-1.dll) but not mingw32-w64 (libgcc_s_sjlj-1.dll).

 Replying to [comment:4 Gilles Mouchard]:
 > Below a patch I apply to boost 1_60_0 to make it compile with mingw
 (both mingw32 and mingw-w64). It is derived from fedora patches. The patch
 forces compiling for NT and adds extra assembly directive for gas.
 > The only stuff that doesn't seem to work is exception handling: a throw
 in a coroutine, for example, invariably results in a call to terminate().
