netpbm-10.30-r1 still segfaults here. I just re-emerged it, because bug #114812 says this segfault is fixed, and I suspected that prelink messed this up. Reproducible: Always Steps to Reproduce: Call pnmtopng without args or with any args (only --help does not segfault here). E.g. I tried "pnmtopng -transparent '#ffffff' action-background.ppm".

Created attachment 75718 [details, diff] Fix for a problem. This patch fix a problem for netpmb-10.31. I think for 10.30 it should work also.
Comment on attachment 75718 [details, diff] Fix for a problem. different issue, file a new bug report
post the actual files that are causing pnmtopng to segfault and the commands you used to make it segfault
# pnmtopng /usr/share/netpbm/pcxstd.ppm Segmentation fault
Created attachment 76436 [details] pnm file that causes pnmtopng to segfault
works fine for me on x86 and amd64 ... your current gdb bt is useless though, so we'll need to generate a proper one ... do this: # CFLAGS='-g -O -pipe' FEATURES='nostrip' emerge netpbm # gdb --args pnmtopng /usr/share/netpbm/pcxstd.ppm
Oh - it works fine if I use CFLAGS='-g -O -pipe'! Only with -O2 I get the segfault: # CFLAGS='-g -O2 -pipe' FEATURES='nostrip' emerge netpbm # gdb --args pnmtopng /usr/share/netpbm/pcxstd.ppm GNU gdb 6.4 [...] This GDB was configured as "i686-pc-linux-gnu"...Using host libthread_db library "/lib/tls/libthread_db.so.1".

can you try upgrading to 10.31 and see if that fixes things for you ?
Yes, 10.31-r1 works fine with the -O2 flag. # locate .ppm | xargs -n 1 pnmtopng >/dev/null also worked fine, not a single segfault anymore.
