I faced an error "ERROR: ctfconvert: die 37: base type without name" when run ctfconvert on some object files which were produced by gcc-4.4.2
The error like this: /opt/onbld/bin/i386/ctfconvert -g -l NDISWRAPPER example.o ERROR: ctfconvert: die 37: base type without name I prepared a small example file and compile it with command line gcc -g -O2 -o example.o -c example.c and two versions of gcc - 4.4.2 and 3.4.3 Then I run dwarfdump example.o on files produced by 4.4.2 and by 3.4.3 $ cat example.c #include <sys/types.h> int main() { return 0; } Below the file from dwarfdump that was produced by gcc 4.4.2 .debug_info COMPILE_UNIT<header overall offset = 0>: <0>< 11> DW_TAG_compile_unit DW_AT_producer GNU C 4.4.2 DW_AT_language DW_LANG_C89 DW_AT_name example.c DW_AT_comp_dir /home/unix/Documents/bugs DW_AT_low_pc 0 DW_AT_high_pc 0x3 DW_AT_stmt_list 0 LOCAL_SYMBOLS: <1>< 37> DW_TAG_base_type DW_AT_byte_size 4 DW_AT_encoding DW_ATE_unsigned <1>< 40> DW_TAG_base_type DW_AT_byte_size 4 DW_AT_encoding DW_ATE_signed DW_AT_name long int <1>< 47> DW_TAG_base_type ...
