Hi,

I'm porting a large application from linux to cygwin.
The app is made of several static libraries and an exe that link to all =
of them.
the build process goes smoothly and the libs/exe are built with no =
trouble.

But the if i try to run the new exe i get (sory in french):
VOTRE APPLICATION A PROVOQUE UNE CORRUPTION MEMOIRE
AX : 0000000000000000
Aborted (core dumped)
(something like YOUR APP  CORRUPTED THE MEMORY)

if i try the same under gdb and put a breakpoint in main :
This GDB was configured as "i686-pc-cygwin"...
(gdb) b main
Breakpoint 1 at 0x401ef4: file tg_main_src/tg_mainStartup.cxx, line 49.
(gdb) r
Starting program: /TANGO/tg_disp_03.00/bin/cygwin/tg_disp.exe

Breakpoint 1, main (argc=3D1, argv=3D0xa011870)
    at tg_main_src/tg_mainStartup.cxx:49
49      {
Current language:  auto; currently c++
(gdb) s
VOTRE APPLICATION A PROVOQUE UNE CORRUPTION MEMOIRE
AX : 0000000000000000
    187 [sig] tg_disp 1184 open_stackdumpfile: Dumping stack trace to =
tg_disp.ex
e.stackdump

Program exited with code 0303000.

So it looks like i can't event go to the first line of real code...

PS : a simple hello_world.c compiles and runs OK, same for a =
hello_world.cxx
the compile options are :

for each .o of static libraries=20
g++ -g -D__unix__ -Wall -Wmissing-prototypes -pipe -D_THREAD_SAFE =
-I./include  -c tg_bus/divers.cxx -o tmp/cygwin/divers.o
ar -rc lib/cygwin/static_lib.a tmp/cygwin/divers.o

for exe
g++ -g -D__unix__ -Wall -Wmissing-prototypes -pipe -D_THREAD_SAFE -o =
tg_disp tg_disp.cxx -L./lib/cygwin -L/usr/local/lib -Lstaticlibs -ltgsys =
-ltgloaddic -ltgbus -ltgdisp

What am i doint wrong ?
