Nightly builds of RISC OS since 2015-07-05 include zero page protection, which forbids accesses to “zero page”, an area of system memory reserved for use by the Kernel.
Some software may still make references to these locations, usually because the programmer has not checked a pointer for validity before using it. Please see this post for a more in depth explanation of what this is about.
A compatibility/logging module called “ZeroPain” is available that logs such illegal accesses and allows the buggy application to continue to run in the short term. The log permits the problems to be identified so that application writers can fix the bugs.
In order to keep duplicated reports to a minimum, the following alphabetical lists record the known status of system components (part of RISC OS itself) and third part softwre (maintained by other authors). If not listed and you find the software fails, simply send the author the log following the general guidance for reporting bugs to give as much detail as possible.
