BUG gmp: crash in config.guess due to mfpvr instruction

[vincent-opdarw@…]

On my Power Mac G5, a crash occurs in config.guess, due to a generated code that contains the mfpvr instruction. This crash can be noticed (and is then annoying) when CrashReporter's developer mode has been enabled.

I think this can be fixed by trapping the corresponding signal (SIGILL?), but I can't currently try because my Mac is under repair.

I forgot to say: the fix must be a DarwinPorts patch since upstream doesn't want this bug to be fixed (see gmp-bugs mailing-list, thread "crash in config.guess on Power Mac G5 under Mac OS X 10.4.6").

I'll take a look.

Vincent,

I have read the exchange in the gmp-bugs mailing list. Does this problem _prevent_ building a working gmp library if the CrashReporter's developer mode is disabled? Or is a proper error code returned by the shell and the configuration procedure continues?

I think that the building goes on normally (ditto if CrashReporter's developer mode is enabled, except that one has this annoying window).

Adding reporter, assignee and myself to Cc: list. Can either of you confirm whether or not bug exists in the current version of the gmp port?

[vinc17@…]

Yes, it still exists. BTW, several months ago, I tried to solve the problem by trapping the signal, but though the signal was trapped, I still got the CrashReporter window appearing.

Since the build does succeed, and the Crash Reporter window is merely an annoyance, fixing this is low-priority.
