boost does not cross-compile for qnx (at least x86_64) since 1.86.0

Cross compiling boost release 1.86.0 on QNX SDP 7.1 (qcc 8.3.0 (with gcc backend)) results in Segmentation Fault.

I tried the following versions:
1.81.0 works ✅
1.85.0 works ✅
1.86.0 seg fault ❌
1.87.0 seg fault ❌
1.90.0 seg fault ❌

I used the following comands on a freshly download version:
`./bootstrap`
`./b2 -j$(nproc) toolset=qcc target-os=qnx architecture=x86 address-model=64 variant=release threading=multi threadapi=pthread link=static runtime-link=static --with-system --with-filesystem --with-thread --with-chrono --with-date_time --with-regex --with-program_options`

The only output I see on the terminal is:
`Segmentation fault (core dumped)`

I cross compile on the following host (lsb_release -a):
