Which application crashes, elf2e32 or the resulting Symbian binary?
The tool is included in the SDK as well, and the SDK has the needed scripts to perform the conversion with all the due parameters. For example an attempt to call the tool with a command similar to yours, presuming "test" to be a valid ELF binary, would generate errors (not crashes) due to missing parameters such as
elf2e32 : Error: E1017: Missing options : --defoutput.
elf2e32 : Error: E1017: Missing options : --dso, --linkas.
