Re: LD producing SegFault executables with FreePascal 2.6.4, in Binutils-2.36.1 and later

Please could you file a bug report about this issue using the binutils
bugzilla system:

  https://sourceware.org/bugzilla/enter_bug.cgi?product=binutils

Has anyone been able to track down the exact cause of the segmentation
fault ?  For example is the loader rejecting the executable as being
malformed, or is the startup code branching off into a random memory
location, or something else ?

Do you know which bug this was ?

Not to be mean, but if the 3.x series is working, why worry about
the 2.6.4 release ?  If people want to use that release, can't they
also stick with binutils 2.35 ?
