I'm dealing with a Fedora GDB bug that is related to PR tui/25126, and I thought I'd write a specific testcase for it because I couldn't find one. The idea is to get the simple reproducer from the bug and tweak the testcase around it. This one was a bit hard because, since we need to modify the source file and recompile it, it involved a bit of TCL-foo to do things. Also for this reason, I'm only enabling the test for native boards. I tested this with an upstream GDB and made sure everything is passing. I also tested with a faulty GDB and made sure the test failed. gdb/testsuite/ChangeLog: 2020-02-11 Sergio Durigan Junior <sergiodj@redhat.com> PR tui/25126 https://bugzilla.redhat.com/show_bug.cgi?id=1784210 * gdb.base/cached-source-file.c: New file. * gdb.base/cached-source-file.exp: New file.

|
The bug is about a regression that makes GDB not reload its source
|
|
code cache when the inferior's symbols are reloaded, which leads to
|
|
wrong backtraces/listings.
|
|
|
|
This bug is reproducible even without using the TUI.
