libgcc: Fix eh_frame fast path in find_fde_tail
|
|
|
|
The eh_frame value is only used by linear_search_fdes, not the binary
|
|
search directly in find_fde_tail, so the bug is not immediately
|
|
apparent with most programs.
|
|
|
|
Fixes commit e724b0480bfa5ec04f39be8c7290330b495c59de ("libgcc:
|
|
Special-case BFD ld unwind table encodings in find_fde_tail").
