Howdy, I am compiling for 64-bit Windows 7 with: make TARGET_SYS=Windows CC="x86_64-w64-mingw32-gcc" HOST_CC="gcc" on 64-bit Fedora. Any Lua error at all causes the program to crash with the following error message: PANIC: unprotected error in call to Lua API ('insert error here') For example: x = "invalid"+5 x = invalid syntax pcall(function() error("wat") end) All three examples do the same thing: crash it with "luajit.exe is not responding." It was suggested on #lua that there is an issue with "unwinding." Adding "XCFLAGS+=-DLUA_USE_APICHECK" and "XCFLAGS+=-DLUA_USE_ASSERT" did nothing I have no idea where to go from here, so any help would be appreciated. Thanks, Declan.
