+@subsection A GNU/Linux Debug Quirk
+
+
+On SuSE 15, some kernels have a defect causing issues when debugging
+programs using threads or Ada tasks. Due to the lack of documentation
+found regarding this kernel issue, we can only provide limited
+information about which kernels are impacted: kernel version 5.3.18 is
+known to be impacted, and kernels in the 5.14 range or newer are
+believed to fix this problem.
+
+The bug affects the debugging of 32-bit processes on a 64-bit system.
+Symptoms can vary: Unexpected @code{SIGABRT} signals being received by
+the program, “The futex facility returned an unexpected error code”
+error message, and inferior programs hanging indefinitely range among
+the symptoms most commonly observed.
