Please follow this guide to provide a better backtrace http://www.gentoo.org/proj/en/qa/backtraces.xml?style=printable Also please run strace -o pcmanfm.log /usr/bin/pcmanfm and attach the pcmanfm.log file Thanks
Created attachment 245538 [details] strace -o pcman.log /usr/bin/pcmanfm hi, I try to use -01 and -ggdb on my CFLAG but I don't think the backtrace output is very much different. Tell me what I miss.
use -ggdb on your CFLAGS and then rebuild libfm and pcmanfm and then attach the new segfault output. That should provide a better backtrace
Created attachment 245544 [details] gdb output Yes I did that. I guess it looks the same on my untrained eyes. Hope this help.
It seems to me that there is a situation of uninitialized pointer (sep) leading to segfault. This comes from libfm _fm_path_init function so this is actually a libfm bug I contacted upstream about that
Could you please try libfm/pcmanfm 9999 and see if it still fails for you? Thanks
It works now. No more segfault.
I guess this is fixed in libfm-0.1.14. Reopen if needed
