Comment 20 for bug 2007642

The crash is in inside_main_function, due to the modifications here:

    commit 9370fd51ebfca8a8acacaecb92c57ee54f4f8382
    gdb: detect main function even when there's no matching msymbol

First, gdb doesn't find the minsym, probably because the msyms
contain:

[99] t 0x90c0 _ZN17rustc_gdb_10317454main17h5b5be7fe16a97225E section .text rustc_gdb_1031745::main::h5b5be7fe16a97225 zko06yobckx336v

... but we're looking for:

(top-gdb) p name
$13 = 0x292e0c0 "rustc_gdb_1031745::main"

The _Z overloading strikes again.

Anyway somehow we find a full symbol for this, but it doesn't
have a block, so the assert fails.
