>Description:

Updating the kernel on this machine to -current breaks tcsh (stock, from pkgsrc),
it dies with:

    16      1 tcsh     CALL  break(0x26b918)
    16      1 tcsh     RET   break -1 errno 12 Cannot allocate memory
    16      1 tcsh     CALL  break(0x26b919)
    16      1 tcsh     RET   break -1 errno 12 Cannot allocate memory
    16      1 tcsh     CALL  break(0x26c118)
    16      1 tcsh     RET   break -1 errno 12 Cannot allocate memory
    16      1 tcsh     NAMI  "tcsh.core"
...

>How-To-Repeat:
Boot a -current kernel, try to exec older tcsh (binary from June 1).

>Fix:
n/a

 Module Name:	src
 Committed By:	joerg

 Modified Files:
 	src/sys/kern: exec_elf.c

 Log Message:
 Remember the end of the last text segment and set up a fake data segment
 if size 0 and starting after the text segments, if no data segment was
 found. Unbreaks sbrk on platforms where all loaded segments are
 executable (PR 43817). The cast of executable segments after data
 segments is left out for now.
