Abseil import causes errors (workaround implemented, issue for further investigation)

[m-olko]

Suddenly, importing abseil is causing some compilation errors. I don't exactly know why, gemini suggested it might be related to new compiler/linker. Currently the error is mitigated by special compilation flags in .bazelrc introduced in #42 but we should investigate further later on.
