An older lldb 3.8 hits the breakpoint just fine. I placed some logging in LLDB:<br>
<br>
ModuleSP DynamicLoader::<wbr>LoadModuleAtAddress(const FileSpec &file,<br>
addr_t link_map_addr,<br>
addr_t base_addr,<br>
bool base_addr_is_offset) {<br>
printf("%s: lma = 0x%16.16llx, ba = 0x%16.16llx, baio = %i\n", file.GetPath().c_str(), link_map_addr, base_addr, base_addr_is_offset);<br>
<br>
<br>
This is called by DynamicLoaderPOSIXDYLD::<wbr>LoadAllCurrentModules().<br>
<br>
My problem is I see:<br>
<br>
[vdso]: lma = 0xffffffffffffffff, ba = 0x00007ffff7ffa000, baio = 0<br>
linux-vdso.so.1: lma = 0x00007ffff7ffe6e0, ba = 0x00007ffff7ffa000, baio = 1<br>
/tmp/liba.so: lma = 0x00007ffff7ff66a8, ba = 0x00007ffff7e30000, baio = 1<br>
8 locations added to breakpoint 1<br>
/tmp/libb.so: lma = 0x00007ffff7e2f000, ba = 0x00007ffff7d43000, baio = 1<br>

/tmp/libc.so: lma = 0x00007ffff7e2f000, ba = 0x00007ffff7d43000, baio = 1<br>
/tmp/libd.so: lma = 0x00007ffff7e2f000, ba = 0x00007ffff7d43000, baio = 1<br>
<br>
<br>
Note that I see program output _during_ the messages that are showing that shared libraries are being loaded? I would assume we are loading shared libraries synchronously, but the log seems to indicated otherwise.<br>
<br>
If anyone knows anything on this subject please let me know...<br>
