the variables elem and file0 and commited are explicitely set to avoid that they get freed in ther waserror() handlers. but it turns out the compiler optimizes this out as he thinks the variables arent used any further. (the compiler is not aware of the waserror() / longjmp() semantics). rearrange the code to account for this. instead of using a local variable to check for point of no return (commited), we use up->seg[SSEG] to figure it out. for file0 and elem, we just rearrange the code. elem can be checked in the error handler if it was already assigned to up->text, and file0 is just free()'d after the poperror(). remove silly busy loop in sysrendez. it is not needed. dequeueproc() will make sure that the process has come to rest. |
