I guess since it's been in WAITING with no response for so long I'll close this as INVALID.

--- Comment #5 from radu dot gcc at ohmi dot org 2009-05-31 01:52 --- Created an attachment (id=17939) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17939action=view) Improved hello-test case showing working and failing command lines, with Makefile This behaviour exists on Linux beam 2.6.22-15-server #1 SMP Wed Aug 20 19:08:24 UTC 2008 i686 GNU/Linux, running gcc version 4.1.3 20080308 (prerelease) (Ubuntu 4.1.2-21ubuntu1) In my case, I found it accidentally, as there was a stray '-static' on the command line, even though I was compiling a shared build. Removing '-static' fixes the problem, but I did bang by head against the wall a couple of times while looking for the problem. The attached testcase shows how this bug is duplicated. It is the same testcase submitted previously, but I added the '-static -shared' combo, as on my system the original testcase did not reproduce the bug. The output from my run is: gcc -o hellomain.o -c -g hellomain.c hellomain.c: In function 'main': hellomain.c:9: warning: incompatible implicit declaration of built-in function 'exit' gcc -o hello_.o -g -c -fpic -DPIC hello.c gcc -o libhello.so -shared -g hello_.o gcc -g -o hello-exec hellomain.o -L. -lhello echo Linking with both -static and -shared flags exposes the bug.
