We need fix in 1.16 too! |
When a DW_FORM_line_strp is used without a debug_line_str section a good error message (about the missing section) is generated but immediately overwritten by the underflow error generated by trying to read the non-existent section.

any change to get this backported? AFAIK otherwise debugging does not work if the application needs gcc to build and gcc is >=11 |
|
@gopherbot Please open backport issues. This change is reportedly required on Windows systems using current versions of GCC. |

Backport issue(s) opened: #50721 (for 1.16), #50722 (for 1.17). Remember to create the cherry-pick CL(s) as soon as the patch is submitted to master, according to https://golang.org/wiki/MinorReleases. |
