Program: import std.file; void main() { readText("nonexisting"); } On my Kubuntu 12.10 VM, I see this when I compile and run it: std.file.FileException std/file.d(214): nonexistent: No such file or directory ---------------- crash(void[] std.file.read(const(char[]), uint)+0x50) [0x8082a00] crash(immutable(char)[] std.file.readText!(immutable(char)[]).readText(const(char[]))+0x16) [0x80807d2] crash(_Dmain+0x14) [0x80807b8] crash(extern (C) int rt.dmain2._d_run_main(int, char**, extern (C) int function(char[][])*).void runMain()+0x10) [0x8081d74] crash(extern (C) int rt.dmain2._d_run_main(int, char**, extern (C) int function(char[][])*).void tryExec(scope void delegate())+0x18) [0x8081a20] crash(extern (C) int rt.dmain2._d_run_main(int, char**, extern (C) int function(char[][])*).void runAll()+0x32) [0x8081db2] crash(extern (C) int rt.dmain2._d_run_main(int, char**, extern (C) int function(char[][])*).void tryExec(scope void delegate())+0x18) [0x8081a20] crash(_d_run_main+0x121) [0x80819f1] crash(main+0x14) [0x80818c4] /lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xf3) [0xf75014d3] ---------------- However, on a Gentoo and an Ubuntu server, I get this: std.file.FileException std/file.d(214): nonexisting: No such file or directory ---------------- crash() [0x804c010] crash() [0x8049de2] crash() [0x8049dc8] crash() [0x804b384] crash() [0x804b030] crash() [0x804b3c2] crash() [0x804b030] crash() [0x804b001] crash() [0x804aed4] /lib32/libc.so.6(__libc_start_main+0xe5) [0xf75cfbb5] crash() [0x8049ce1] ---------------- For some reason, backtrace_symbols is returning an empty string. addr2line has no issue with decoding the addresses, however. If I copy a binary compiled on one machine to another, its behavior is preserved, so it appears to be something in the build environment (and not the execution environment). It's not the D compiler... does anyone know what might cause this? (gcc / ld version?)
