Strange crash when linking static.

Fri Oct 1 21:20:00 GMT 2004

Hi there!
I have a strange problem when building my static linked application that 
usses JNI and Network.
During linking I get the following message which does not sound too bad:
/usr/lib/gcc-lib/i386-redhat-linux/3.3.3/libgcj.a(gc_dlopen.o)(.text+0xbc): 
In function `GC_dlopen':

runtime the shared libraries from the glibc version used for linking

java::net::InetAddress*, bool)':

/usr/lib/gcc-lib/i386-redhat-linux/3.3.3/libgcj.a(natInetAddress.o)(.text+0x22f):

java::net::InetAddress*, bool)':

looks quite fine, however does anybody know a way to make static builds 
independent from a shared glibc?
Hmm, but thats not my real problem.
If I start the application, I get the following:

this rt_sigprocmask-syscall is repeated all the time, somtimes with some 
brk-syscalls mixed.
I tried to debug the whole thing using gdb, however gdb says that it 
faild setting a breakpoint in a shared library.
After this message gdb blocks the terminal and killing this gdb even 
killed the bash running gdb ;-)
Any ideas whats wrong? I use gcj-3.3.3 distributed with Fedora Core 2....
Any help would be very welcome. since I am not the type of hacker that 
could solve such problems by hand :-(
Btw. The dynamic linked version works perfect and a static linked hello 
world also works perfect.
Thanks a lot, lg Clemens Eisserer
PS: "Thanks for this great software", everytime I use it this words come 
in my mind. Its so great, really great!! Its amazing what you can do 
with GCJ.
