Second repost as this has not got through to list yet ... I really have trouble to get that standalone/prefer applet working again within Busybox ash scripts. Other applets of Busybox seam to fail in same way, not only awk. Need help!
Hi !
I stumbled on some trouble. After modifying a few scripts to use
Busybox ash instead of bash, I hit on a case where glibc aborts with:
glibc detected /bin/busybox: munmap_chunk(): invalid pointer
(Full error output appended)
After narrowing that down, I found this happens when Busybox calls the
awk applet using the preferred applet feature, but works correct if awk
is invoked manually or with /bin/busybox awk.
I have appended the following:
- Busybox shell script (w)
- awk script (w.awk)
- example input file processed by the awk script (w.txt)
- the full output including error message (w.err)
- my Busybox configuration (busybox.config)
- map file from Busybox compile (busybox_unstripped.map)
[removed due to size limit of mail list, asked if you need a copy]
I used at least two different Busybox versions 1.20.1 and snapshot from
2012-07-31 with same type of error message.
