--- Comment #11 from Zoltan Hidvegi <zoltan at hidvegi dot com> --- Do you have more info regarding the AIX assembler bug you are referring to? PR46072 was about a different assembler bug, it's just someone in that report have also encountered the stabstring length issue. I was under the impression, that the assembler does not interpret the stab continuation at all, it just puts stabstring entries as is into the xcoff object file, and the continuation is needed because of the 64k limit imposed by the XCOFF32 object file format, and therefore multiple stab entries would be present in the .o file for long stabs and the debugger is supposed to handle that as if it was a single long stabstring.
