File gdb-6.5-sharedlibrary-path.patch of Package gdb
If you provided some relative path to the shared library, such as with export LD_LIBRARY_PATH=. then gdb would fail to match the shared library name during the TLS lookup. Dropped the workaround/fix for gdb-6.8.50.20081128 - is it still needed? The testsuite needs `gdb-6.3-bz146810-solib_absolute_prefix_is_empty.patch'. The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'. 2006-09-01 Jan Kratochvil <jan.kratochvil@redhat.com> * solib-svr4.c (svr4_fetch_objfile_link_map): Match even absolute requested pathnames to the internal loaded relative pathnames. 2007-10-16 Jan Kratochvil <jan.kratochvil@redhat.com> Port to GDB-6.7. 2008-02-27 Jan Kratochvil <jan.kratochvil@redhat.com> Port to gdb-6.7.50.20080227.
