stack trace for crash
This is expected and when you link against recent glibcs it even warns you about it. If a program uses NSS/iconv/dlopen or locales, it is not self-contained and as such can be only used against the same glibc as it has been compiled/linked against. Better avoid statically linked programs, dynamically linked ones are way more portable. |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Description of problem: A statically linked executable compiled on RH7 or earlier crashes in gethostbyname() on RH9. Happens both with a clean RH9 install as well as with the latest glibc. It works okay if the program is compiled statically on RH9. It appears to be an incompatibility with the nss_files.so static hack (which works with all previous versions of Linux right back to pre-glibc2 versions). Version-Release number of selected component (if applicable): 2.3.2-27.9.7 How reproducible: Always Steps to Reproduce: 1. (on RH7): g++ -static tester.cpp 2. (on RH9): ./a.out test.com 3. Actual Results: Segmentation fault Expected Results: 208.48.34.132 Additional info:
