Not sure we're familiar with this one unfortunately. @jonathanmetzman have you seen this before? |

seem this might be due to duplicate symbols: https://cgit.freedesktop.org/libreoffice/core/commit/?id=658946e0353c2fad5e26bb75f851744da4b7751f |

This enables fuzz introspector for lua. The [current build](https://oss-fuzz-build-logs.storage.googleapis.com/log-95e09fbf-701e-4adf-ad25-8629c7dd5f8a.txt) fails with: ``` Step #6 - "compile-libfuzzer-introspector-x86_64": [Log level 1] : 10:13:22 : This means a main function is in the source code rather in the libfuzzer library, and thus we do not care about it. We only want to study the actual fuzzers. Exiting this run. Step #6 - "compile-libfuzzer-introspector-x86_64": /usr/bin/ld.gold: internal error in read_header_prolog, at ../../gold/dwarf_reader.cc:1678 Step #6 - "compile-libfuzzer-introspector-x86_64": clang-15: fatal error: linker command failed with exit code 1 (use -v to see invocation) Step #6 - "compile-libfuzzer-introspector-x86_64": make: *** [makefile:119: lua] Error 1 Step #6 - "compile-libfuzzer-introspector-x86_64": ``` At first I thought this was an issue of multiple-definitions since the error is the same as: #8629 However, allowing multiple definitions didn't work. I'm not entirely sure why this fixes the problem. It was through trial and error I came up with the fix. I assume it may be some ASAN gets compiled in somehow during non-ASAN builds and this causes issues for the gold linker (but not in non-gold linkers, i.e. coverage and other sanitizers are fine). This fixes the introspector build, but also adds ASAN instrumentation which bloats the calltrees, but the function table is good. I tried setting LDFLAGS=-fsanitizer=address but this didn't work in the case of Lua. I have some ideas, however, to fix this. Will pursue that at a later stage. Ref: #10882

recent libreoffice builds are failing with:
/usr/bin/ld.gold: internal error in read_header_prolog, at ../../gold/dwarf_reader.cc:1678
which isn't something I've seen happen before. Any recent toolchain changes?
