Still have some tests failing. For instance tests/buf fails with the following error message: iconv(&<"abcd">, &<4>, &s, &<3>) caused a SIGSEGV! I am not sure but it seems that iconv() that is called from wrap_iconv() should return an error return value and set an errno value. At least to my understanding that the way the test is written. For musl implementation of iconv() returns 0 and sets no errno. While in the case of standard Linux implementation, errno = E2BIG and -1 returned ( error return value) . For the case buf linked dynamically against the standard libc.so library: ldd tests/buf libpthread.so.0 => /lib64/libpthread.so.0 (0x00000030d1000000) librt.so.1 => /lib64/librt.so.1 (0x00000030d4400000) libm.so.6 => /lib64/libm.so.6 (0x00000030d0800000) libc.so.6 => /lib64/libc.so.6 (0x00000030d0400000) /lib64/ld-linux-x86-64.so.2 (0x00000030cf400000) > uname -a Linux lnxbdc96 2.6.18-164.11.1.el5 #1 SMP Wed Jan 6 13:26:04 EST 2010 x86_64 x86_64 x86_64 GNU/Linux Can you please look into this ? Thanks.
