Constructor with parameters imported from C++ is not called when --exceptions:goto

[demotomohiro]

Description

When constructor with parameters imported from C++ is called, default constructor is called instead.
This happens only when compiled with --exceptions:goto option, doesn't happen with --exceptions:cpp and exceptions:quirky.

Example:
testcpp.nim

{.emit:"""/*TYPESECTION*/
struct CppClass {
  int x;

  CppClass(): x(0) {}
  CppClass(int x): x(x) {}
};
""".}

type
  CppClass {.importcpp.} = object
    x: cint

proc constructCppClass(x: cint): CppClass {.importcpp: "CppClass(@)", constructor.}

proc main =
  let cppClass = constructCppClass(123)
  echo cppClass.x

main()

Compile it with nim cpp -r --exceptions:goto testcpp.nim.

Additional Information

Nim generated C++ code compiled with --exceptions:goto:

N_LIB_PRIVATE N_NIMCALL(void, main__testcpp_u5)(void) {
	NimStringV2 colontmpD_;
	CppClass cppClass{};

Nim generated C++ code compiled with --exceptions:cpp:

N_LIB_PRIVATE N_NIMCALL(void, main__testcpp_u5)(void) {
	...
	try {
	CppClass cppClass(((int)123));

[demotomohiro]

Calling constructor with parameter after declaring the variable can workaround this problem as long as it has default constructor.
Following code works correctly.

Example:

{.emit:"""/*TYPESECTION*/
struct CppClass {
  int x;

  CppClass(): x(0) {}
  CppClass(int x): x(x) {}
};
""".}

type
  CppClass {.importcpp.} = object
    x: cint

proc constructCppClass(x: cint): CppClass {.importcpp: "CppClass(@)", constructor.}

proc main =
  var cppClass: CppClass
  cppClass = constructCppClass(123)
  echo cppClass.x

main()

In Nim generated C++ code:

N_LIB_PRIVATE N_NIMCALL(void, main__testcpp_u5)(void) {
	CppClass cppClass{};
	...
	cppClass = CppClass(((int)123));

Unfortunately --exceptions:goto break in a few places the C++ backend

I dont think there is a solution for it other than dont use goto or use an initializer:

proc constructCppClass(x: cint = 123): CppClass {.importcpp: "CppClass(@)", constructor.}
