Yocto Project
We distribute two main recipes, one for testing/dev purposes and other with the latest stable release.
When Fluent Bit series v1.0.x is build for an AArch64 target platform, the default backend mechanism for co-routines will be sigaltstack(2), if the compiler flags specified _FORTIFY_SOURCE, it will generate an explicit crash with an error message similar to this one:
Fluent Bit v1.1.0 which is under active development on GIT Master, already integrates native AArch64 support where stack switches for co-routines are done through native ASM calls, on this scenario there is no issues as the one faced with _FORTIFY_SOURCE in previous 1.0.x series.
