stepping over longjmp

With current CVS GDB and Fedora Core 5 i686 i386 GNU/Linux (2.6.17-1.2157 but
also 2.6.15) when I try to step over longjmp (using next) I get the following
error:

Warning:
Cannot insert breakpoint -59.
Error accessing memory address 0x226092c5: Input/output error.

ISTR that this was also the case with FC4 and have only recently realised that
you can step usefully step over a longjmp call after trying it on Mandrake 9
(2.4.19)

Is this a known kernel problem or a bug in GDB?
