If you provided some relative path to the shared library, such as with
|
|
|
2c2fa1 |
export LD_LIBRARY_PATH=.
|
|
|
2c2fa1 |
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'.
|
|
|
2c2fa1 |
The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
