This is a summary to a question never asked, but I hope it is sufficiently
helpful to be an admissible posting.

The problem:
Running configure for a package using the GNU Autotools crashes my GS1280,
Tru64 V5.1B PK4 with "System panic: panic (cpu 0): Bigpage Assert Failure".
Bigpage support is enabled on my machine.

The cause:
The package uses libtool, and thus runs the AM_PROG_LIBTOOL macro as part of
configure, which in turn calls AC_LIBTOOL_SYS_MAX_CMD_LEN. The latter macro
tries to determine iteratively how long a command line may be. Now I had
configured my system with proc:exec_disable_arg_limit=1, ie, permitting
infinitely long command line arguments.

I have posted a pertaining bug report on the libtool mailing list and hope
they'll fix the macro.

Two questions/suggestions in this respect:
- - Is there a command to directly query the maximum command line length?
- - Could HP introduce a tunable limit for the length, instead of just a
  limit/no-limit switch?

Best regards,
Hans
