------- Additional Comments From bjoern dot m dot haase at web dot de 2005-02-09 23:14 ------- Maybe this will help to localize the origin of the bug a bit better: I have made the observation that the presence of the bug strongly depends on the size of the memory footprint of the structs. Maybe there is a problem when the stack frame starts to grow beyond the 128 Byte boundary. Yours, Björn -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18251
