Bug#322972: icon: ftbfs [sparc] Tests failed: ilib sorting table

[Jurij Smakov]

tags 322972 patch
thanks

Hi,

I was able to track this bug to line 198 in src/runtime/fmisc.r:

   dst-table.defvalue = src-table.defvalue;

Assembly code generated for this line attempts to copy the defvalue 
structure by doing a single double-word load and store, even though the 
defvalue structure is only aligned on a word-boundary. This causes 
an unaligned trap resulting in the bus error. Tracking the problem down is 
rather tricky, however the quick-and-dirty solution is to replace this 
line by an explicit memcpy(). Attached patch implements this change, with 
it icon builds successfully, passing all the tests.


Best regards,
