1109,[with patch] gp interface raises stack overflow exception if gp stack exceeds available memory,cwitty,was,"The gp interface automatically runs allocatemem() to double the Pari stack size if it gets a response back from gp that includes ""the PARI stack overflows"", and then re-executes the failing command.  However, if gp cannot grow the stack further, allocatemem() will simply print a warning message and do nothing; then the interface gets stuck in a loop.  (This gives a stack overflow, rather than an infinite loop, because the re-execution is handled by a recursive call.)

I'm attaching a patch that shows one way to fix this; it notices when allocatemem() fails and simply returns the original stack-overflow error message.  (I'm not sure if this is the best approach; would it be better to raise an exception here?  Somebody familiar with the gp interface should comment.)",defect,closed,major,sage-2.8.12,interfaces,fixed,,,,,,,,,
