Description Jesse Keating 2009-03-19 19:15:20 UTC 
Rawhide from 20090319 booting boot.iso both i386 and x86_64 no other options results in a SIGSEGV:

loader received SIGSEGV! Backtrace:

Comment 1 David Cantrell 2009-03-19 19:39:14 UTC 
This is because some doPwMount() calls are passing NULL for the last parameter rather than always passing a double pointer.  In doPwMount(), I'm trying to dereference the last parameter as a double pointer, so when it's NULL...bang.

Preparing a new boot.iso to test with.
Comment 2 David Cantrell 2009-03-19 21:12:19 UTC 
Patch sent to list for review.  Built a local boot.iso to test and it's working.  New boot.iso image for today's tree can be found here:

No longer seeing this with anaconda-11.5.0.34.  Tested both i386 and x86_64 boot.iso's

Comment 4 James Laska 2009-03-20 13:25:41 UTC 
I'm running into bug#491326 now, but that's after the original SIGSEGV
