17 | # symtabs created by another objfile sharing the same BFD. | |
18 | # | |
19 | # It mimics how a bug with psymtab sharing was initially found: | |
20 | # | |
21 | # 1. Load the test file twice, such that the second objfile re-uses the | |
22 | # per_bfd object created for the first objfile. | |
23 | # 2. Run to some point where in the backtrace there is a frame for a | |
24 | # function that's in a CU that's not yet read in. | |
25 | # 3. Check that this frame's information is complete in the "backtrace" | |
26 | # output. | |
