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? -- Nick http://www.inet.net.nz/~nickrob
