Hi,
the following problem occures if I start gdb with a program linked
against pthread and try to run this program twice:
----------------------------------------------------
pthread-test> gdb ./test_thread
GNU gdb 5.0

This GDB was configured as "i386-suse-linux"...
(gdb) run
Starting program: /hosts/zeppelin/users1/harry/pthread-test/./test_thread
[New Thread 1024 (LWP 22955)]
Program exited normally.
(gdb) run
Starting program: /hosts/zeppelin/users1/harry/pthread-test/./test_thread
/hosts/zeppelin/users1/harry/pthread-test/./test_thread: error while loading
shared libraries: libpthread.so.0: failed to map segment from shared object:
Cannot allocate memory
Program exited with code 0177.
(gdb)
----------------------------------------------------
The source for the program is:
----------------------------------------------------
int
main (int argc, char **argv)
{
return 0;
}
----------------------------------------------------
Compiled with:
g++ -pipe -march=i586 -g -fPIC -shared -D_REENTRANT -c -o test_thread.o
test_thread.cpp
Linked with:
g++ -g test_thread.o -lpthread -o test_thread
Version of g++ is 2.95.3
The glibc and pthread-library is the one from the SuSE-distribution version 7.1
and is from the package: glibc-2.2-7.i386.rpm
regards
Harald
