This PR adds beautiful segfaults ❤️ .

Then ran this on one occurring in pcre: <details> <summary>Backtrace</summary> ``` > "Segmentation fault: 11" Stack trace (most recent call last): #10 Object "Main.exe", at 0x103150c2b, in camlCore_scan.scan_5956 + 123 #9 Object "Main.exe", at 0x1053e6883, in caml_start_program + 131 #8 Object "Main.exe", at 0x1029a1db3, in caml_program + 56027 #7 Object "Main.exe", at 0x1029b5627, in camlDune__exe__Main.entry + 111 #6 Object "Main.exe", at 0x104bedf4b, in camlUCommon.exn_to_real_unixexit_351 + 51 #5 Object "Main.exe", at 0x104be221f, in camlCommon.protect_307 + 39 #4 Object "Main.exe", at 0x10501fddb, in camlStdlib__Fun.protect_326 + 107 #3 Object "Main.exe", at 0x104bee203, in camlUCommon.pp_do_in_zero_box_432 + 51 #2 Object "Main.exe", at 0x104bee703, in camlUCommon.fun_1206 + 51 #1 Object "Main.exe", at 0x1029eab17, in camlPro_core_CLI.run_898 + 1687 #0 Object "Main.exe", at 0x103150c3c, in camlCore_scan.scan_5956 + 140 ``` </details> and a marshalling segfault out in the wild: <details> <summary>Backtrace</summary> ``` Stack trace (most recent call last): #31 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #30 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #29 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #28 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #27 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #26 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #25 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #24 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #23 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #22 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #21 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #20 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #19 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #18 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #17 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #16 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #15 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #14 Source "src/pro_scan/Pro_scan.ml", line 606, in camlPro_scan.scan_exn_4292 [0x60bdb7] #13 Source "src/core/opentelemetry.ml", line 1312, in camlOpentelemetry.with__2580 [0x23b2f52] #12 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #11 Source "OSS/src/core_scan/Core_scan.ml", line 738, in camlCore_scan.fun_7477 [0xbe214b] #10 Source "OSS/src/core_scan/Core_scan.ml", line 628, in camlCore_scan.parmap_map_5319 [0xbe4c67] #9 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #8 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #7 Source "OSS/libs/parallelism/Parmap_.ml", line 169, in camlParmap_.parmap_479 [0x238ccbe] #6 Source "OSS/libs/commons/Common.ml", line 53, in camlCommon.protect_307 [0x240497b] #5 Source "/root/.opam/5.3.0/.opam-switch/build/ocaml-compiler.5.3.0/stdlib/fun.ml", line 34, in camlStdlib__Fun.protect_326 [0x27bf47a] #4 Source "src/parmap.ml", line 401, in camlParmap.mapper_1352 [0x2390ca3] #3 Source "src/parmap.ml", line 115, in camlParmap.unmarshal_860 [0x238f495] #2 Object "/usr/lib/python3.12/site-packages/semgrep/bin/semgrep-core-proprietary", at 0x30a695a, in caml_c_call #1 Source "runtime/intern.c", line 993, in caml_input_value_from_block [0x308b6fb] #0 Source "runtime/intern.c", line 762, in caml_parse_header [0x308a109] ``` </details> synced from Pro a5dc2cd7fd0d8736642572760d2ff6a05adbed4e
