g++ 3.4.4: all global constructors in archive not called


Dear cygwin readers,

I have just ported an application from Linux to Cygwin.
In one archive (.a) I have several global constructors,
2-3 in two .o files.  When I run my program only one
initializer function is called in that archive. Leaving
the other uninitialized/uncalled.

I have found this issue reported in 2002, but there
is no solutions posted in response to this question.

http://sourceware.org/ml/cygwin/2002-07/msg00447.html


To verify this problem I created a simple class and made a local global instance. The class name and output string was slightly different in the other file.

class a_very_local_t {
public:
    a_very_local_t() {
	printf("arbfragprog.cc: very_local_t::constructor\n");
	_info = 0;
    }
private:
    int _info;
};

static a_very_local_t a_local_instance_a;


When the program is started I only get the output from one of the .o files (the first alphabetically).

It appears to me a rather fundamental issue that should have
been solved years ago. Have I missed to provide the compiler/linker/archiver with an appropriate flag?


Thanks in advance for your help.

best regards / Patric
