In order to print unicode characters with llvm, I used setLocale in llvm ir:
call i8* @setlocale(i32 6, i8* getelementptr inbounds ([1 x i8]* @pe,
i32 0, i32 0)) nounwind
where @pe is defined as follows:
@pe = private unnamed_addr constant [1 x i8] zeroinitializer, align 1
However, I got the following error:
*** glibc detected *** ./test/bin/executable: free(): invalid next size
(fast): 0x08f93140 ***
I used gdb to debug the program and the backtrace is as follows:
#0 0xb7728424 in __kernel_vsyscall ()
#1 0xb74aee71 in raise () from /lib/i386-linux-gnu/libc.so.6
#2 0xb74b234e in abort () from /lib/i386-linux-gnu/libc.so.6

#4 0xb74ef961 in ?? () from /lib/i386-linux-gnu/libc.so.6

#8 0xb74a5299 in ?? () from /lib/i386-linux-gnu/libc.so.6
#9 0xb74a4cd1 in setlocale () from /lib/i386-linux-gnu/libc.so.6
...
How can I resolve this issue? Any help would be appreciated

Hi Ali, did you link your program statically? Try linking it dynamically. Ciao, Duncan.

Hi Ciao, my compiler is written in java and generates some .ll files as its output. Each of these .ll files is converted to an object file using llc. Then, I use clang++ to link them and generate an executable file without linking with any external libraries, so I cannot understand what you mean.
