Thanks !

I applied the patch. 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)

Can you please look into this ?

Thanks.
