[DynInst_API:] Crash in Elf_X.C, when running test_driver

["Mikhail T." <mi+thun@xxxxxxxxxxxxxxxxx>]

Hello!

I'm trying to make a FreeBSD port of dyninst. The code builds (targets: all, parseThat, and test-full), but, when I attempt to run the test_driver, only the first 4 tests pass. The driver crashes after that:

TEST                       COMP   OPT  ABI MODE     THREAD  LINK    PIC     RESULT
test2_2                           none 64  create   NA      dynamic nonPIC  PASSED
test2_1                           none 64  create   NA      dynamic nonPIC  PASSED
test_pt_ls                        none 64  create   NA      dynamic nonPIC  PASSED
test_pt_ls                        none 64  rewriter NA      dynamic nonPIC  PASSED
Segmentation fault (core dumped)

According to gdb, the crash is inside Elf_X.C:

#0  0x00000008047e54a7 in Dyninst::Elf_X_Data::get_verDefSym (this=0x7fffffffaaf0) at ../src/Elf_X.C:808
808         return new Elf_X_Verdef(is64, data->d_buf);
(gdb) p is64
$2 = true
(gdb) p this
$3 = (Dyninst::Elf_X_Data * const) 0x7fffffffaaf0
(gdb) p *this
$4 = {data = "" is64 = true}

I'm on FreeBSD-9.1/amd64 and setting PLATFORM to amd64-unknown-freebsd7.2. The runTests-program is unusable:

../../../dyninst/scripts does not exist.  Paradyn scripts dir required.

so I am trying to use the test_driver directly. Other than PLATFORM and LD_LIBRARY_PATH, do I need to set some other env-variables, perhaps?

Please, advise. Thank you!
