Here is what I found so far. I am on openSUSE Tumbleweed 20241129 with ltrace-0.7.91+git20230705.8eabf68 installed. I am dabbling in some programming tasks of my own and tried to used ltrace to find a bug in my own software. While doing so I got to see malloc(ltrace: type.c:100: type_struct_add: Assertion `field_info->type != ARGTYPE_VOID' failed. [1] 17111 IOT instruction (core dumped) ltrace ./test more than I liked. I started to experiment a little, first with C: #include <stdlib.h> #include <stdio.h> int main() { void* ptr = malloc(100); printf("Hello World!\n"); free(ptr); return 0; } $ gcc -o test -O0 test.c $ ltrace ./test I get the expected output: malloc(100) = 0x1c83e2a0 puts("Hello World!") = 13 free(0x1c83e2a0) = <void> +++ exited (status 0) +++ Doing the same with debug information turned on $ gcc -o test -O0 -g test.c $ ltrace ./test Same result, it works as expected. Switching to C++: #include <cstdlib> #include <print> int main() { void* ptr = malloc(100); std::println("Hello World!"); free(ptr); return 0; } $ g++ -o test -std=c++23 -O0 test.cpp $ ltrace ./test produces the expected result: malloc(100) = 0x2bc872b0 memchr("Hello World!", '{',12) = nil memchr("Hello World!", '}', 12) = nil memcpy(0x7ffcbea03640, "Hello World!", 12) = 0x7ffcbea03640 memcpy(0x7ffcbea03750, "Hello World!", 12) = 0x7ffcbea03750 memcpy(0x7ffcbea03840, "Hello World!\0", 13) = 0x7ffcbea03840 memchr("{}\n", '{', 3) = 0x41a15a memchr("{}\n", '}', 3) = 0x41a15b memcpy(0x7ffcbea035c0, "Hello World!", 12) = 0x7ffcbea035c0 memchr("\n", '{', 1) = nil memchr("\n", '}', 1) = nil memcpy(0x7ffcbea035cc, "\n", 1) = 0x7ffcbea035cc fwrite("Hello World!\n", 1, 13, 0x7fc1a61fd5c0) = 13 free(0x2bc872b0) = <void> +++ exited (status 0) +++ But turning on debug information: $ g++ -o test -std=c++23 -O0 -g test.cpp $ ltrace ./test reproduces the error: malloc(ltrace: type.c:100: type_struct_add: Assertion `field_info->type != ARGTYPE_VOID' failed. [1] 8307 IOT instruction (core dumped) ltrace ./test That is what I was experiencing while searing for bugs in my own programs. They are written in C++ and I was on a build with debug settings. Then ltrace fails in the same way. Release builds of my programs where fine as show above with the test programs. I switched compilers from g++ 14.2.1 to clang++ 19.1.4 but the problem remains. However, grabbing the upstream sources (https://gitlab.com/cespedes/ltrace.git) and compiling ltrace 0.7.91 on my machine does NOT reproduce the problem. I get the expected output: malloc(100, 0x7ffd63d18868, 0x7ffd63d18878, 0x563399116bd8) = 0x5633d167e2b0 memchr(0x56339910d4a8, 123, 12, 12) = 0 memchr(0x56339910d4a8, 125, 12, 12) = 0 memcpy(0x7ffd63d183f0, 0x56339910d4a8, 12, 0x7ffd63d17d78) = 0x7ffd63d183f0 memcpy(0x7ffd63d18500, 0x7ffd63d183f0, 12, 15) = 0x7ffd63d18500 memcpy(0x7ffd63d186b8, 0x7ffd63d18500, 13, 0x7ffd63d18500) = 0x7ffd63d186b8 memchr(0x56339910d4b5, 123, 3, 3) = 0x56339910d4b5 memchr(0x56339910d4b5, 125, 3, 3) = 0x56339910d4b6 memcpy(0x7ffd63d18340, 0x7ffd63d186b8, 12, 0x7ffd63d17a68) = 0x7ffd63d18340 memchr(0x56339910d4b7, 123, 1, 1) = 0 memchr(0x56339910d4b7, 125, 1, 1) = 0 memcpy(0x7ffd63d1834c, 0x56339910d4b7, 1, 0x7ffd63d17c98) = 0x7ffd63d1834c fwrite(0x7ffd63d18340, 1, 13, 0x7f27317fd5c0) = 13 free(0x5633d167e2b0, 0x5633d167e320, 0, 0x7ffd63d186b8) = 5 +++ exited (status 0) +++ I then grabbed the source rpm ltrace-0.7.91+git20230705.8eabf68-2.2.src.rpm from download.opensuse.org-oss, rebuild it locally, installed it and this too fails as before.
