I just put here 3 ślokas from BPHS (from chapter 82/80 ‘Strī jātaka’). Interesting, that G.Ch.Sharma, R.Santhanam, P.N.Sharma and S.Ch.Mishra editions have the similar versions of these ślokas, whereas in the edition of Devachandra Jha the meaning 2nd shloka is different (he adds condition of houses from the Moon, and in houses from the Moon he also considers Saturn as doṣa – see the details below). In editions of Tara Chandra, Girdhari Lal and Ganesh Datt Pathaka I have not found such chapter and ślokas.
All the above publications say that if Mars has an aspect or conjunction of a benefic planet, then Mangalika Doṣa will not be there. And the verb hanti I translated as "to destroy" (from the root 'han' - to hit, to beat, to pound, to thrash, to strike, to kill, to beat, to kill, to spoil, to destroy, to execute, to prevent, to cause pain, to wound the heart), since it does not necessarily mean 'death'. An interesting meaning of this word is 'to beat').
Also please note that all the above mentioned authors say that if Mangalika Doṣa is present for both spouses, then there will be an auspiсious result, doṣa is canceled (which confirms the Russian proverb "there is no defense against a crowbar, if there is no other crowbar...").
Please see below translation of two versions and also a few illustrations.
And note the order of houses in the 1st śloka in Devachandra Jha's edition - first comes the 4th house, then the 1st, then the 7th, 8th and 12th. Perhaps this is the order of decreasingdanger of Mangalika Doṣa.
अथ स्त्रीजातकाध्यायः ॥ ८०॥ atha strījātakādhyāyaḥ ||80|| Translation: Now (atha) the chapter about female horoscope (strī-jātaka-adhyāyaḥ).

G.Ch.Sharma, R.Santhanam, P.N.Sharma, S.Ch.Mishra: लग्ने व्यये सुखे वापि सप्तमे चाऽष्टमे कुजे । शुभदृग्योगहीने च पतिं हन्ति न संशयः ॥४७॥ lagne vyaye sukhe vāpi saptame cā’ṣṭame kuje | śubhadṛgyogahīne ca patiṃ hanti na saṃśayaḥ ||47|| Translation: If Mars (kuje) (in the female horoscope) is in the Lagna, in the 12th house, the 4th house, the 7th house or the 8th house (lagne vyaye sukhe vā-api saptame ca-aṣṭame) and bereft of the aspect or conjunction of the auspicious planets (śubha-dṛg-yoga-hīne ca), it will certainly destroy the husband (patiṃ hanti na saṃśayaḥ). *** Devachandra Jha- pati-ghātaka-yoga (yoga of destroying the husband) पाताले ऽपि तनौ रन्ध्रे जामित्रे वापि च व्यये । स्थितः कुजः पतिं हन्ति न चेच्छुभयुतेक्षितः ॥४८॥ pātāle ’pi tanau randhre jāmitre vāpi ca vyaye | sthitaḥ kujaḥ patiṃ hanti na cecchubhayutekṣitaḥ ||48|| Translation: If Mars is located (sthitaḥ kujaḥ) in the 4th, in the 1st, in the 7th, in the 8th or the 12th house (pātāle ’pi tanau randhre jāmitre vāpi ca vyaye) and devoid of auspicious yoga or aspect (na ced-śubha-yuta-ikṣitaḥ), it will destroy the husband (patiṃ hanti).

G.Ch.Sharma, R.Santhanam, P.N.Sharma, S.Ch.Mishra: स्त्रीहन्त्रा परिणीता चेत् पतिहन्त्री कुमारिका । तदा वैधव्ययोगस्य भङ्गो भवति निश्चयात् ॥४९॥ strīhantrā pariṇītā cet patihantrī kumārikā | tadā vaidhavyayogasya bhaṅgo bhavati niścayāt ||49|| Translation: If (cet) a man with yoga of destroyer of wife (strī-hantrā)marries (pariṇītā)a woman with yoga of destroyer of husband (pati-hantrī kumārikā), then (tadā) there will be certainly (bhavati niścayāt) a cancellation of widowhood yoga (vaidhavya-yogasya bhaṅgo).

If [this yoga is] in the horoscopes of both (ubhayoś-ced), then auspicious result is declared (śubhaṃ smṛtam).
