No I cannot. The version of Valgrind I use was ported on QNX in 2015 by open QNX community (https://community.qnx.com/sf/go/projects.valgrind/frs.valgrind.valgrind_3_10) and, as far as I know, no newer version was ported since.

Excellent idea. If I use "--tool=none", valgrind does not crash anymore (and I suppose it doesn't do much).
At least, it seems to mean that the problem is linked to the tool I use. However, for all other tools I try (massif, drd, helgrind, exp-dhat) I face the same crash.
