I have a program compiled under SAS/C. It starts up several iterations of a child process using the 2.0 function System(). The child program was compiled under gcc. The first iteration comes back fine. But when the second comes back, the A5 register is corrupted. And then a few statements later GURU, 80000004 (or 81000004, don't remeber). This is the only know problem with these programs (the parents stack space is getting messed up). If I manually change the A5 register, at the end of each iteration, back to the correct value, the probram behaves. Does anybody have any theories? Oh, by the way let's make a silly assumption that my code is ok. Is there a problem with mixing compilers like this? Is gcc doing bad housecleaning?
