I have build a GCC-6.1.0 cross compiler with SJLJ exceptions on Ubuntu 16.04
LTS. Using the cross compiler I build a native GCC-6.1.0 with SJLJ
exceptions for Windows. The host and target for the native compiler was both
configured to i686-pc-mingw32. The build for the cross compiler was set to
x86_64-pc-linux-gnu. The program I tried to run:
#include <iostream>
using namespace std;
int main()
{
auto lambda = [](auto x){ return x; };
cout << lambda("Hello generic lambda!\n");
return 0;
}
The compiler and linker on Windows work as expected, but the compiled
executable crashes. I ran the code through the GDB debugger and it breaks on
line 74 of the <iostream> header. This crash only happens with shared code,
not the static. Below is the debugger output:
Debugger name and version: GNU gdb (GDB) 7.11
Child process PID: 268
In ?? () ()
#1 0x004015f8 in __static_initialization_and_destruction_0
(__initialize_p=1, __priority=65535) at

At c:\mingw\include\c++\6.1.0\iostream:74
Cannot find bounds of current function
Maybe I configured the cross compiler or native compiler incorrectly,
because I downloaded GCC-5.3.0 with SJLJ exceptions from MinGW-w64 and
compiled the above code and that executable works perfectly. Any help will
be appreciated.
